Like charges repel each other, and opposite charges attract each other. The electric force is a non-contact force that does not require objects be touching in order to act. Instead, the electric force acts through an electric field. The strength of the electric forces two objects exert on each other depends on the charges of both objects, as well as the distance between them.
