Amazing amazing explanation.I Cannot describe in words how thankful I am to you sir,from last 1 hr this topic was giving me a headache,Thank You Sir.😀😀👌👌👍👍❤️❤️
Sir plz clear one doubt U calculated the potential through work done by force due to field but in definition it is external force and ext. Force is opposite to field force
Sir but you've find potential using conservative force instead of external force... Since the work done by ext force gets stored in charge in form of potential energy not due to electric force??? So i think there should be negative dign
But potential is equal to negative of work done by conservative force and equal to work done by external force ...you should add negative here at the end to get potential because u have taken work done by conservative force here
That's wrong. Because you're initially calculating Workdone by Electric Force. And it comes out to be positive... Which is wrong. Electric force is doing negetive work here. You're taking the direction part two times. W ( external ) = - W ( electric )
Great teaching effort sir... But, you've considered ELECTRIC FORCE while calculating the work Whereas while calculating potential we always consider work done by EXTERNAL FORCE, which is in the same direction as displacement (dx) Then, shouldn't the value of theta be taken 0°
I am very grateful to you that I take out at my time and I comment on your video so that you should know how good teacher you are aapane Itna achcha explain Kiya ki mujhe ek hi bar Mein samajh a Gaya aur Main Apne friends ko bhi samjha sakti hun
I generally Used to watch pw video but when I saw you I literally loved it , because of your teaching accent you make me to realise that physics is Not tough anymore aur sir apke videos se mere physics k derivation bhot easy hogyi hai
Sir, I have an doubt on one hand you have said work done by external force while on other hand you are calculating work done by electrostatic force . In most of the books same procedure is given. how is it possible?
Electrostatic force to obviously lgna e h but apn ne external force lgaya (in the opposite direction of the electrostatic force k) taaki charge ka acceleration na ho
Note: In bringing the charge we are creating an external force of the test charge towards the Source charge. Since the Fext is in the direction of displacement we get cos0=1 but we are bringing the test charge very slowly such that there is no net force on the test charge and thus no acceleration on it . This step happens very slowly such that Magnitude of Fext is equal to Force due to electric field created by source charge but the direction of Fe (Force by electric field) is opposite to the Fext . Vector Fext=-vector Fe So, we replaced Fext with -Fe . We can also understand it by saying the direction of displacement of test charge is opposite to Fe so, Cos180 =-1 so, we got this answer. Why we needed to replace Fext by Fe? Because it was easier for us to find the value of Fe

Aur bhai sir to Galat padha rahe hain, angle will not be 180😠😠😠
Then kya hoga agar 180 nhi hei toh?
Sir i like your channel because of these short videos that sum up all the main points in a quick manner👍this helps me a lot..thank you sir🙏
Welcome 🙂

Sir your board work is so smooth that I admire your handwriting.....and sir You cleared all my doubts in a very brief period of time ....A BiG THANKS
But how has it been explained in NCERT ..it's confusing
Yes that's why I searched this on youtube
You give lot of information in short period of time 🙏 thanks

This video help me so much thanks a lot sir🙏🙏
Sir your teaching way is so god
Your explanation is too good
Sir Your teaching skill are good
I have nothing to say about sir because everything is Umesh sir .
Your teaching method is very good I happy
Great explanation sir ❤
Great work 🎉
Wrong ans
dw is work by electric field not us
Sir apka teaching to kamaal ka hai ❤
Thanks sir ... Pura derivation easy ho gaya 🤍
Sir thank you so much

Sir but you've find potential using conservative force instead of external force... Since the work done by ext force gets stored in charge in form of potential energy not due to electric force??? So i think there should be negative dign
Sir reply toh krdo mere question ka???
Yes bro.... work is done by external force...and negative is due to ... negative rate of change...as velocity is negative as x is decreasing ...
But potential is equal to negative of work done by conservative force and equal to work done by external force ...you should add negative here at the end to get potential because u have taken work done by conservative force here
Sir
thank u ❤ can u help me with how to find questions ❓ on that topic
sir your handwriting is amazing
Sir writing bahut acchi hai apki
Good explanation sir☺☺
Thanks
I really appreciate you sir aapne Mera pura concept clear kar diya 👍
Thanks sir I used find it difficult but you have made it very easy
That's wrong. Because you're initially calculating Workdone by Electric Force. And it comes out to be positive... Which is wrong. Electric force is doing negetive work here. You're taking the direction part two times.
W ( external ) = - W ( electric )
Sir what will happen if we take - Q...
Sir can we take negative Q charge instead of positive Q charge in this calculation...?
Great teaching effort sir...
But, you've considered ELECTRIC FORCE while calculating the work
Whereas while calculating potential we always consider work done by EXTERNAL FORCE, which is in the same direction as displacement (dx)
Then, shouldn't the value of theta be taken 0°
Ur teaching style is damn awesome sir....... 🙏
Amazing sir you are wodurful thank you sooo much

Electric force and displacement are in opposite direction then how can work is positive.....can you explain?
Magnitude of work is considered

Sir, I have an doubt
on one hand you have said work done by external force while on other hand you are calculating work done by electrostatic force .
In most of the books same procedure is given.
how is it possible?
Very good question bro this question also bothered me
Electrostatic force to obviously lgna e h but apn ne external force lgaya (in the opposite direction of the electrostatic force k) taaki charge ka acceleration na ho
Note: In bringing the charge we are creating an external force of the test charge towards the Source charge. Since the Fext is in the direction of displacement we get cos0=1 but we are bringing the test charge very slowly such that there is no net force on the test charge and thus no acceleration on it . This step happens very slowly such that Magnitude of Fext is equal to Force due to electric field created by source charge but the direction of Fe (Force by electric field) is opposite to the Fext .
Vector Fext=-vector Fe
So, we replaced Fext with -Fe . We can also understand it by saying the direction of displacement of test charge is opposite to Fe so, Cos180 =-1 so, we got this answer.
Why we needed to replace Fext by Fe? Because it was easier for us to find the value of Fe
That's amazing sir
