1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution (a) Shown. (b) W = 975 MeV (c) Initially nucleus has volume V. Splits into two smaller particles each with charge Q/2, and volume V/2. So for each particle, Q/2 and R*(1/2)1/3 So, W' ~ 2 * [(0.5)2/(0.5)1/3] = (0.5)2/3 ΔW = 360 MeV I'm not sure if the volume of each is halved or not by their phrasing..
