The figure provided shows the potential energy of a proton, q = +e, and a lead nucleus, q = +82e. If a proton is fired toward a lead nucleus from very far away with kinetic energy K = 3.00×10-12 J, how much kinetic energy does it have when it is 20.0 fm from the nucleus and moving toward it, before the collision?  5.00×10-12 J  4.00×10-12 J  3.00×10-12 J  2.00×10-12 J
