Namaste sir, My peers and I had a question and would be grateful if you considered explaining the answer to us. The question is as follows If you are inside the box which is moving with constant velocity and you have all kind of physics equipment you want. What experiment will you do to determine that you are in motion?(no external observer is there)
Good morning sir. Many books and coaching center modules provide an equation for FORCE BETWEEN TWO POINT CHARGES KEPT IN A DIELECTRIC MEDIUM .In that equation k (dielectric constant) is found as an extra quantity in denominator , as compared to force between two point charges in free space . Now my question is why should force between two charges change due to change in medium? Doesn't the word BETWEEN refers to ACTION - REACTION pair between the two charges ? How can ACTION - REACTION pair change even if new charges due to polarization also come into action because SUPERPOSITION PRINCIPLE says force between two charges doesn't change by presence or absence of third charge(s) . And using this equation some some books have even given expression for force BETWEEN two point charges when medium inbetween them is partially filled with dielectric by using the equation . I haven't seen any well reputed book containing such equations. Hope Sir you will surely discuss this in any of your videos.
Because in medium we have electrons protons etc. So, they create polarization thats why that polarization decrease the force ,for better understanding read about polarization
@@AvikGupta-ch7oh But what about superposition principle which says action- reaction force between two charges is not affected if you bring some other charges ...whether by polarization or by any other method ? Why does Sears & zemansky say on page 696 : "Strictly speaking, Coulomb’s law as we have stated it should be used only for point charges in vacuum"
Guess what, you're right. The coulombic force between two charges is ALWAYS of magnitude F = (1/4piε0) q1q2/r^2, independent of the medium between them. But, in case there is a dielectric medium between them, then there are other induced/polarised charges in the medium whose forces we also need to consider, to get the net force on a charge. In the case of two like charges in a medium, the NET FORCE (repulsive) on a charge will be effectively decreased, as there are induced charges in the medium which attract this charge. So, what books usually refer to when they say that the "electrostatic force decreases in a dielectric medium", is actually that "the net force on a charge will be less than the actual coulombic force, due to induction of charges". Depending on the properties of the medium, we see that this "reduction of force" is usually linearly proportional to the original force itself, which is why this reduction can be signified, just by dividing the force by the constant, (which can be calculated, and is K (dielectric constant), characteristic of a medium's extent of polarisation) To summarize, the COULOMBIC FORCE due to q1 on q2 is still the same. But in presence of a medium there are other charges, which when accounted for, give a NET FORCE to be reduced by the K-factor.
@@DipamSen Thanks a lotttttt. Actually so called authors have made a mess. In place of writing NET FORCE ON A CHARGE IN A MEDIUM is given by........, they write FORCE BETWEEN TWO CHARGES IN A MEDIUM is given by......... The language BETWEEN refers to mutual action -reaction which in no way can mean same as NET FORCE ON A CHARGE. Another point is that regarding this equation of force between two charges in a medium is that in his book Richard Feynman says ( naming this equation as 10.29) " Most older books on electricity start with this equation . This is a point of view which is thoroughly unsatisfactory. For one thing it is true only for a world filled with a liquid and for material in general k is only appropriately constant. Thanking you one again for the time given.
@@jsaifi7402 Here's a quote from the same chapter that I found while reading, which talks about this point: "Today we look upon these matters from another point of view, namely, that we have simpler equations in a vacuum, and if we exhibit in every case all the charges, whatever their origin, the equations are always correct. If we separate some of the charges away for convenience, or because we do not want to discuss what is going on in detail, then we can, if we wish, write our equations in any other form that may be convenient." (Here separation of charges for convenience refers to not taking into effect the induced/polarised charges and the forces due to them, but just calculating the net force by dividing the coulombic force by K)
Lecture delivered in unknown language and subtitles also delivered in unknown language just code mixing with English. Now I have to drop this comment and run wishing that i had completely watched it.
there is no meaning as such. its a useful quantity and each has different application. dot product - it can tell how similar two vectors are. for 0 angle its max. for pi/2 its 0 and for pi it's -1. vector product is used to find normal to two vectors. its useful for displaying graphics. for e.g. in raytracing a light vector falls on the object and then calculates cross product with the surface normal vector which tells it where light will bounce to. this happens for every pixel and the light ray bounces for a set number of times. so when you play a game with rtx on. 1920*1080*x calculations are happening every 1/fps time. and now do this for 4k. gpus are powerful

Hello sir I have a question.... please give me the answer of the question 🙏 What is the difference between this two questions 1) two hollow spheres have radii r1 and r2 have same charge on their surface. ratio of electric potential??? 2)two hollow spheres have radii r1 and r2 have same electric field on their surface. ratio of electric potential???
So in first it is saying the charges are same so it is not necessary that electric field and potential will be same as there radii are not same... But in second question if electric field is same at the surface then it means that the charges and radii of two spheres are not same.. Their ratios are same but the individual charges and there radii both are different in second case..
I am Ayush from 10th class. In my book(NCERT), the potential difference is defined as difference of electric potential between two points in an electric circuit carrying some current as the work done to move a unit charge from one point to the other. In this definition there are three major things that are distance, energy consumed aur work done, quantity of electrons moved. So the formula should be 1volt = 1 joule*1metre/1 coulumb But why distance is ignored...?

Guess what, you're right. The coulombic force between two charges is ALWAYS of magnitude F = (1/4piε0) q1q2/r^2, independent of the medium between them. But, in case there is a dielectric medium between them, then there are other induced/polarised charges in the medium whose forces we also need to consider, to get the net force on a charge.

To summarize, the COULOMBIC FORCE due to q1 on q2 is still the same. But in presence of a medium there are other charges, which when accounted for, give a NET FORCE to be reduced by the K-factor.

there is no meaning as such. its a useful quantity and each has different application.
dot product - it can tell how similar two vectors are.
for 0 angle its max. for pi/2 its 0 and for pi it's -1.
vector product is used to find normal to two vectors.
its useful for displaying graphics. for e.g. in raytracing a light vector falls on the object and then calculates cross product with the surface normal vector which tells it where light will bounce to. this happens for every pixel and the light ray bounces for a set number of times.
so when you play a game with rtx on. 1920*1080*x calculations are happening every 1/fps time. and now do this for 4k. gpus are powerful
Then what is meaning of addition 😮
@@shivangsingh5834 addition and subtraction have just simple meaning. they find resultant. it joins tail of one vector to head of another and then finds and resultant

Very good I wish I knew so well

Hello sir I have a question.... please give me the answer of the question 🙏
What is the difference between this two questions
1) two hollow spheres have radii r1 and r2 have same charge on their surface. ratio of electric potential???
2)two hollow spheres have radii r1 and r2 have same electric field on their surface. ratio of electric potential???
So in first it is saying the charges are same so it is not necessary that electric field and potential will be same as there radii are not same...
But in second question if electric field is same at the surface then it means that the charges and radii of two spheres are not same..
Their ratios are same but the individual charges and there radii both are different in second case..
@User213-z5f Thnx dear 🙏❤️

This legend ☝️focuses on teaching more than exposing himself...as others do.... Digital board k jamana a Gaya lekin ...black board ko nhi choda 👏👏👏
Thankyou sir for always being for is❤❤
Dearest sir, why are you not starting coaching centre for physics..It will be great helpful for the aspirants and students will be luckiest one🙏
We love you hc sir ❤❤❤❤😊😊😊
Sir I have questions for you sir can you tell me ... Does water vapour rise up in vaccum?
It is a miracle that I passed maths and physics in my 12th Board exams. I have no fucking idea what the hell is written on that blackboard.

Sir, please also solve some questions of mechanics
It will come in the series.
I am Ayush from 10th class.
In my book(NCERT), the potential difference is defined as difference of electric potential between two points in an electric circuit carrying some current as the work done to move a unit charge from one point to the other.
In this definition there are three major things that are distance, energy consumed aur work done, quantity of electrons moved.
So the formula should be 1volt = 1 joule*1metre/1 coulumb
But why distance is ignored...?
Do study for boards kid!

Thanks for your support I crack itt Mumbai
When plate is moving with uniform velocity in uniform magnetic field then same flux will pass through the plate all the time because everything is uniform then how flux changes and emf developed in such circumstances. Please explain Sir.
Sir you are legend
Yeh wave function to kisi imaginary wave ka hai, kyunki wave ka speed order of 21 pe hai, jo light ki speed se bohot bohot zyaada hai
