Question

the sphere of radius R is placed in uniform electric field E the inward electric flux is given by​

Answer 1

Answer:

E(πr²)

Explanation:

The net flux on a surface is defined as Gaussian integral of E multiplied by the effective Area. Since the Sphere doesnt enclose any extra charge, net flux of sphere is zero

Hence, Flux on outside = Flux on inside.

Therefore, E*(Effective Area) = E * πr²

If you have a doubt on how it is πr², It's because the Effective Area enclosed when you look from one side will be πr².
