Electrostatics doubt maybe........
I Have finished my electrostatics chapter today, i have decided to start the PYQs, i have MTG PYQ book (47+23 years)
there are 219 questions 😭 now the thing is, my 11th concepts aren't good. so should i work on 11th or proceed with the pyqs?
also, ye saare pyq karun ki selected questions?
i regret buying this pyq set for 2k INR
i should have bought 1 year subscription of exam goal for 150 INR
😭

Electrostatics Basics
Let's say we took a neutral body which has special charge arrangement such that all the negative charge is on one side, now the positive side of the body is connected it to Earth, so Earth gives electrons to neutralize the body.
My question is, how did electrons move without any Potential Difference?
haven't studied 2nd chapter yet

Electric Flux
Why electric flux due to charge outside the gaussian surface is zero.
i know 2 explanations,
1. Qinside/ε₀ = 0 as there isn't any charge inside the gaussian surface.
2. Jitni Field lines enter kar rahi hain, utni hi exit kar rahi so flux total = 0
But can someone please explain if we try integrating E.dA vector, we get 0 for charge outside.
integrate karke zero kaise aaega?
