Homework Statement
Charge is distributed on the surface of a spherical balloon (an insulator). 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)
Homework Equations
F = kqq/r^2
The Attempt at a Solution
I thought it would be "a" because their would be more differences in forces the closer the charge is to the surface.
The correct answer is "e". I do not understand why :(.
