Question

You put charge on a metal. Which are true? (Might be more than one. Choose all that apply)

A.) The electric potential of the surface is zero.

B.) The electric field is constant at the surface.

C.) The electric field is perpendicular to the surface.

D.) The electric potential is constant over the surface.

E.) The electric field is zero at the surface.

Answer 1

when a metal is charged, all the charges resides on the outer surface of the conductor. The electric potential is constant on the surface and inside the conductor. the electric field is perpendicual to the surface of a charged metal. Also, the elctric field is constant on the surface of the metal

.the true options are:

B.) The electric field is constant at the surface.

C.) The electric field is perpendicular to the surface.

D.) The electric potential is constant over the surface.
