2. When uranium 235U captures a neutron, it fissions (splits) into two nuclei (and emits several neutrons, which can cause other uranium nuclei to split). Assume that the fission products are equally charged nuclei with charge +46e and that these nuclei are at rest just after fission and separated by twice their radius 2R=1.3 x 1014m. (a) Calculate the electrostatic potential energy of the fission fragments. (b) Find the electric field at point P located a distance x = 3R from the origin.
