Homework Help: physics

Posted by rick on Wednesday, January 30, 2008 at 7:51pm.

An electron and a proton are initially very far apart (effectively an infinite distance apart). They are then brought together to form a hydrogen atom, in which the electron orbits the proton at an average distance of 5.11 10-11m. What is EPEfinal - EPEinitial, which is the change in the electric potential energy?
