👍👍👍👍 good but I don't understand
Mg
😂😂
🤣
Bro Hindi wale video dekha lee 🥲🥲
HAHAHAHAHAH
Woah, that was INSANE! Dude you're one heck of a teacher, Like I rarely understand conepts this good. Thanks a ton mate!
Ncert is totally focusing on maths part, and the actual concepts of PHYSICS aren't getting into head. BUT this is exactly HOW I would want physics to be explained. THANK YOU soooo much 🙏
😮😮😮😮
Ncert was focusing too much on binomial theorem and the mathematics while it still used alot of approximation , you my beautiful teacher explain it in the correct way needed❤
Finally got what textbooks/teachers did not bother to teach. Thank from the bottom of my heart❤️
Dude I have to admit, you are so good
Nothing changes even if you don't admit.
Dude this guy is the go to for any thing i dont understand from the textbook
Why is he so damn good. The explanation was Top notch. Just Flawless. Love u Khan Academy❤
THANKS A LOTT for taking time to explain why you didn't substitute in the numerator..... It really made me feel like i've learnt something new. Unlike any other teacher in India who would just ignore it and looking at that would ruin my mood to study and brings up hate towards this education system. You've earned your subscription.
Thank you soo much for this
following khan academy videos is making me realize how overcomplicated ncert is, that for no reason at a lot of places. this derivation for example is done there using binomial theorem. sir on the other hand made it so simple to understand. thanks a lot.
Ur teaching skills r damn good sir✨🔥 ...normally I wouldn't get anything into my brain but ur teachings r so good ... tqsm 🙏🏻👍
Welcome
Your teaching is awesome sir.
I love your way of teaching!
But I have to admit,
After seeing all these approximations if a Mathamatician saw this,
He will commit suicide.😅
how are you so good but no one knows about you like wow
You are the best teacher there is
Wow I just like opened youtube looking for the answer to that r1-r2 problem, which kept on knocking on my conscience while I was teaching my junior this concept, without knowing myself the proper way of substituting in this one. And I stumbled upon this video, it seems like this video is god's gift😅❤️ thanks
Your teaching style is very good! I feel the excitement that you feel while explaining!
Wonderful
This playlist is invaluable.
Awesome teaching 👏
Simply the best and most to the point explanation.
I rarely comment in anything, but the way u have given the aspects to analyse this derivation ...I'm hypnotized me ..I never even expected this kind of..... Hat's off. Respect for you .
Requesting you to bring more such types of analytical videos plz.
thank you sir for explain this please can you also hold live doubt sessions please sir as many people face many doubts thank you sir
you can ask your doubt here itself !!
Hey you are so good at explanations
It's incredible😍
A big thanks to you sir!
Discovered your channel lately but still from now onwards i'll be constant here
You must be crowned the prince of all teachers in the world
Hey , did you get the video , where he derive the potential in a point charge ?
@@Nancy_Shorts13 you have to see the expression of potential at point P that was derived earlier. You need to see that here. The difference of R1 and R2 is used to define the potential. Similarly, when he derive the difference between R1 and R2 as two a cost theta, then he substituted the same in the earlier equation, thereby resulting in the main formula.
THE BEST
I LOVE YOU FROM BRAZIL ❤🇧🇷
after 3 videos, 5 derivation and spending almost 1 hr now i got to know the exact reason thank you for this amazing video
u forget to put a minus sign too as r1 comes from negative Q and r1is greater than r2
Excellently resolved the problem .the error part was awesome . Keep shining KHAN ACADEMY...
favuolus you did it in an easy and much understandable way , thats amazing !
Easygoing 😇
Bro I literally love u
this simulation thing is really nice
You are very good underrated educator
Universe class content.😯😮
Thanks a lotttttttt, sir
My favorite Physics teacher ❤️❤️❤️
THE GOAT
Wholesome content. I am never gonna forget this concept.
the percentage error really did it for me, thanks
Woww...
awesome ..............i have no word for this explanation ...awesome
omg this much cooll explanationnn
Thanks a lot for such good explanation sir
Hi... I just wanted to say that this video was amazing, so thank you!... How will this equation change if we have an ion as P?
Great video but didnt saw the dervation that i had a doubt in (ncert derivation) ❤
Excellent 💥
Just awesome . Thank you soooo much you make it very intresting 👍
Best explanation ever👏👌, your enthusiasm and excitement is super adorable💖
I really appreciate that u r giving such a high quality education just free of cost!!! Really appreciate your efforts we can't even get this kind of education after paying high amounts of money.
Literally amazing🎉
But i didnt understand why we take perpendicular,
Btw ur teaching style make physics interesting man.
Awesome explanation 👌👌, became a fan of your teaching 🙌
Amazing explanation. Wow simply superb , out of this world explanation ❤️❤️❤️
But Mahesh!
When I solve r1-r2
I.e r1-r1-2a cos theta
I get -2a cos theta
Which will be
-KPcos theta /r²
So what am I doing wrong ?
Superb explanation 👌👌👍👍
Can we calculate that distance by the dipole on the equatorial plane formula?
Hayee !!!! How hard you work..!! :-)
Brilliant😍 Thank u😊
This was the shittest thing to derive till the moment this video had started and now it's my favorite derivation to do again n again 😂
5:15
If you were my teacher in uni right now I will get good grades, fr.
The R1 and R2 looked like 9L1 and 9L2..got me puzzled for a while😂
Anyways this was great
On a general point E=kp/(r) ^3 underoot(3cos^2+1) and V=kpcostheta/(r) ^2
From
dV=E.dr
After integration we got a totally different formula howw????
When you factored out KQ from the equation for VsubP; why do you have r1-r2/r1*r2? Wouldn't you get 1/r2-r1?
Nvm
Its because you don't know how math works.
Oh my god this guy is making me fall for physics
holy moly tysmmm i love this guy(no homo😂)
Why don't we take the point P near to the negative charge?....
in my book there is a two page proof ! this didn't even use half page...
physics no more a nightmare :)
1st view
us
I want u to be my teacher....
Why we take cos theta.....plz.....explain
Because we need to substitute ∆r and it is the cosine that contains ∆r.
But...what if P is near the dipole 🤐
Ok, why is Khan academy India better than khan academy America..............lol jealous that you guys get him all to yourselves!
bro stop the fake accent
Sir please 🙏 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏teach in hindi 🙏
Idk why but his accent bothers me🥲
I came here to find the reason for taking 2a.cos@ as ∆r but you answered questions that didn't even have. So thank you and this is a very nice video!
At first the assumption that they are the same got me curious, but its used is such a genius way!!
