Easy EPE problem

I keep getting 4.259 e-18 and don't know what I'm doing wrong 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 5.41 x 10-11m. What is EPEfinal - EPEinitial, w ...continues
