Ak lectures sir please explain the concept of "" d square""" ... Is this equation is only applicable for 2 point charges or many charges if many chrges then explain concept of d square...?
Coulomb's law is only applicable for two point charges. However when you have other configurations, you use Superposition, which means just keep applying Coulomb's law for every unique pair of charges in your situation. So if you have three point charges (Q1, Q2, and Q3) then to find the force on Q1 you use Coulombs law to find the force on Q1 due to Q2, let's call this F1. You then use Couloumb's law to find the force on Q1 due to Q3, let's called this F2. Superposition then says the total force on Q1 due to both Q2 and Q2 is equal to (F1 + F2).
Great lecture, but ....In the 2nd and 3rd equation, you have equated vector and scalar. I know it doesn't matter but it's good to be mathematically correct at all times
The description of the forces is also inaccurate. F(1,2) is the Force by q1 experienced by q2. His explanation says the opposite. The colour illustrations are spot on though
Coulomb's law is an empirical law, it means it was not derived from other facts about nature. It's an observable law and was found purely by experiment. The results of the experiments showed that it follows an inverse square law.
Thank you for your videos. They are helping me a lot!
mefsio13 you're welcome! :)
These are so useful. Thank you!
Thank you for not adding an intro to all your videos!! excellent video too!
Thank you very much! You did a great job.
❤ good one there

what if a negative mass exists, does it pull a positive mass?
What does electro static force mean
i think it means force exerted by an electron (or a charged particle) that's not in motion, ie not a current.

Van Deusen gang rise up
Why should we take d squared instead of d or d cubic. Please Explain.

I think physics is not Ur favourite subject gentleman....
