Charge Is Distributed on the Surface of a Spherical Conducting

Multiple Choice

Charge is distributed on the surface of a spherical conducting shell. A point particle with charge q is inside. If polarization effects are negligible the electrical force on the particle q is greatest when:

A) it is near the inside surface of the balloon
B) it is at the center of the balloon
C) it is halfway between the balloon center and the inside surface
D) it is anywhere inside (the force is same everywhere and is not zero)
E) it is anywhere inside (the force is zero everywhere)
