Homework Help: AP PHYSICS

Posted by Becky on Wednesday, March 26, 2008 at 6:02pm.

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 5.29*10^.11m. What is the change in EPE(electric potential energy)?


i need help with this problem. please guide me to do it. thanks!
