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..

Both spheres get V/2, right. The density of nuclei is roughly constant, so volume is conserved in nuclear reactions.
