Question

Prove that an excess charge added to the isolated conductor moves entirely to its outer surface.None of the excess charge is found within the body of conductor

Answer 1

Conductors have free charges that are free to move throughout the conductor. When subjected to an external field, the charges will experience a force and will move to the surface in response to the field. Any excess charges added to the conductor will also move to the surface. This phenomenon will result in a net field of zero inside the conductor.
