Answer to Question #131960 in Mechanics | Relativity for Syed Arbas Ali

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.
