If a conductor has a potential `V != 0` and there are no charges anywhere else outside, then

A

there must be charges on the surface or inside itself.

B

there cannot be any charge in the body of the conductor.

C

there must be charges only on the surface.

D

both (a) and (b) are correct.

Text Solution

Verified by Experts

The correct Answer is:
D
If a conductor has a non zero potential and there are no charge anywhere else outside , then there must be charge on the surface of the conductor or inside the conductor. There cannot be any charge in the body of the conductor.
