A spherical charged conductor has surface density of charge as `sigma`. The electric field intensity on its surface is `E`. If the radius of the surface is doubled, keeping `sigma` uncharged, what will be the electric field intensity on the new sphere ?

`E//2`

`E//4`

`2 E`

`E`

Text Solution

Verified by Experts

The correct Answer is:

`E = sigma // epsilon_0` does not depend upon radius if `sigma` is constant.
