Question

Why do charges reside only on the outer surface of a charged conductor?

Answer 1

Hey mate

A charge will always reside on the surface as that's only place left.Because if charge resides inside then by gauss law, field inside the conductor will not be zero........

Electric field inside the conductor will always be zero because if there were any field then free electrons in the conductor will move away.Now when electrons move electrostatics is over and electrodynamics starts as electrostatics is the study of charges at rest and here the case will be opposite, charges would be moving.......

Answer 2

Answer:

Since the electric field is zero inside the conductor, the mutual repulsion of like charges from Coulomb's Law demands that the charges be as far apart as possible. Hence on the surface of the conductor, the net electric charge of a conductor resides entirely on its surface.
