The surface density on a copper sphere is `sigma`. The electric field strength on the surface of the sphere is

A

`sigma`

B

`sigma//2`

C

`sigma//2epsilon_0`

D

`sigma//epsilon_0`

Text Solution

Verified by Experts

The correct Answer is:
D
d. Electric field at any point near the surface of an arbitary
conductor is `E = sigma//epsilon_0` where `sigma` is the surface
change density at that point.
