# Question

An electron that is a certain distance from a proton is acted on by an electrical force.

(a) If the electron were moved twice that distance away from the proton, would the electrical force be (1) 2, (2) 1/2, (3) 4, or (4) 1/4 times the original force? Why?

(b) If the initial electric force is F, and the electron were moved to one-third the original distance toward the proton, what would be the new electrical force in terms of F?
