Question

The charge supplied to a good conductor always resides :

• A. at the supplied position itself
• B. on its outer surface
• C. inside the body
• D. all of the above

Answer 1

The correct option is B on its outer surface

Charge distributing itself on the surface, thereby maximizing the distance between neighbouring repulsive charges and minimizing the overall potential energy, is an equilibrium condition. That is, if you left the system for an infinitely long time to settle, that's the state it would end up in.

Thus the charge always resides on the surface of conductor.

Option B is correct.
