@beautyofeverything7444 2 года назад

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 🙏

Woah, that was INSANE! Dude you're one heck of a teacher, Like I rarely understand conepts this good. Thanks a ton mate!

@sudishtjha1997 7 месяцев назад

Dude this guy is the go to for any thing i dont understand from the textbook

@Dootsauce Год назад

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❤

@abhinavbodybuilderanonymous Год назад

Finally got what textbooks/teachers did not bother to teach. Thank from the bottom of my heart❤️

@sneett7670 2 года назад

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.

Why is he so damn good. The explanation was Top notch. Just Flawless. Love u Khan Academy❤

@krnvrm05 5 месяцев назад

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.

@pipuldewan1582 3 года назад

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.

@savithadas7073 2 года назад

Ur teaching skills r damn good sir✨🔥 ...normally I wouldn't get anything into my brain but ur teachings r so good ... tqsm 🙏🏻👍

Welcome

@kabeerkumar4334 3 года назад

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

@mathletics6287 3 года назад

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.😅

@Nancy_Shorts13 3 месяца назад

Hey , did you get the video , where he derive the potential in a point charge ?

@varun3992 2 месяца назад

@@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.

@vigneshmukundhan8575 3 года назад

@gupt_uv Год назад

u forget to put a minus sign too as r1 comes from negative Q and r1is greater than r2

Literally amazing🎉 But i didnt understand why we take perpendicular, Btw ur teaching style make physics interesting man.

@Ummitsharsh 5 месяцев назад

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 ?

@ananyaaaaaaaaaaaaaaaaaa Год назад

Can we calculate that distance by the dipole on the equatorial plane formula?

@mbongudennis4589 3 года назад

The R1 and R2 looked like 9L1 and 9L2..got me puzzled for a while😂 Anyways this was great

@hookem3768 3 года назад

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?

@hookem3768 3 года назад

Nvm

@uditraj5729 2 года назад

Its because you don't know how math works.

@edupedia2249 2 года назад

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????

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 😂

@hemasreevaliveti7952 3 года назад

Why don't we take the point P near to the negative charge?....

@tejaswini2943 6 месяцев назад

Oh my god this guy is making me fall for physics

@nayyersultana6970 3 года назад

Why we take cos theta.....plz.....explain

@prasoonjha6314 Год назад

Because we need to substitute ∆r and it is the cosine that contains ∆r.
