The liquid-drop model of the atomic nucleus suggests high-energy oscillations of certain nuclei can split the nucleus into two unequal fragments plus a few neutrons. The fission products acquire kinetic energy from their mutual Coulomb repulsion. Assume the charge is distributed uniformly throughout the volume of each spherical fragment and. immediately before separating each fragment is at rest and their surfaces are in contact. The electrons surrounding the nucleus can be ignored. Calculate the electric potential energy (in electron volts) of two spherical fragments from a uranium nucleus having the following charges and radii: 38e and 5.50 10-15 m. and 54e and 6.20 10-15 m.

Alpha particles which have a charge +2e and mass 6.64 ✕ 10−27 kg are initially at rest and are fired directly at a stationary lead nucleus (charge +82e) at a speed of 1.05 ✕ 107 m/s.

Assume the alpha particles are initially very far from a stationary lead nucleus.
When the nucleus of uranium-235 (92 protons and 143 neutrons) absorbs an additional neutron, it undergoes a process called nuclear fission in which it breaks into two smaller nuclei. One possible fission is for uranium nucleus to divide into two palladium nuclei, each of which has 46 protons and 5.9 x 10−15 m in radius. The palladium nuclei then fly apart (their separation if essentially infinite) due to their electric repulsion. If (immediately after the fission) we assume that the palladium nuclei are at rest and are just touching each other, what is their combined kinetic energy when they are very far apart? [Hint: Use the conservation of mechanical energy equation.]
