Electric Potential Energy  Newton’s law for the gravitational force and Coulomb’s law for the electrostatic force are mathematically identical Thus the general features we have discussed for the gravitational force should apply to the electrostatic force In particular we can infer correctly that the electrostatic force is a conservative force. Thus when an electrostatic force acts between two or […]
