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

Options

A. Their 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. there must be charges inside the surface

Answer

A, B

Explanation

From the knowledge of theory, if a conductor has a potential `V != 0` and there are no charges anywhere elese outside, then there must be charges on the surface of conductor of inside the conductor. However, there cannot be any charge in the body of the conductor
Choices (a) and (b) are correct.
