An electron and a proton have charges of an equal magnitude but opposite sign of 1.6 10-19 C. If the electron and proton in a hydrogen atom are separated by a distance of 5.4 10-11 m, what are the magnitude and direction of the electrostatic force exerted on the electron by the proton?

I don't really understand Coulomb's Law... HELP!!
