An electron that is a certain distance from a proton is acted on by an electrical force. If the electron were moved twice that distance away from the proton, would the electrical force be 2, 1/2, 4, 1/4 times the original force? If the initial electric force is F , and the electron were moved to one-fifth the original distance toward the proton, what would be the new electrical force in terms of F ?
