A uranium nucleus with a charge of 92e can spontaneously decay into a thorium nucleus of charge 90e and an alpha particle of charge 2e. The mass thorium is 234 u and that of alpha particle is 4 u. Assume that just after the decay, the decay products are 7.4 x 10^-15 m aparr and at rest
(a) what is the initial potential energy?
(B) find the final kinetic energy of the alpha particle assuming the thorium is at rest.
