Question

The static electric field inside an object made from a conducting material is ____

a.) greater than the electric field just outside the object.

b.) unaffected by the presence of the conductor.

c.) perpendicular to the surface of the object.

d.) constant, but not necessarily zero.

e.) zero everywhere.

Answer 1

The static electric field inside a conductor is zero
Since the charge resides only on the surface of the conductor, the free charges inside the conductor is zero
According to the Gauss's law, since the Gaussian surface contains no charges, the electric field inside the Gaussian surface is zero
The answer is (e)
