Solve the all parts of following question:
Question: Fission of a uranium nucleus (containing 92 protons) produces a barium nucleus (56 protons) and a krypton nucleus (36 protons). The fragments fly apart as a result of electrostatic repulsion. Suppose the two nuclei ultimately emerge with a combined total of 194 MeV of kinetic energy.
Part A: Use this information to estimate the size of the uranium nucleus; that is, treat the barium and krypton nuclei as point charges?
Part B: Calculate the separation between them at the start of the process?
Explanation and formulas needed for best answer! Thanks.
