Expert Answer
Let m1 and m2 are masses of disintegrated nuclei.
Let m1 moves with speed v and m2 moves with speed 2v after disintegration.
By momenetum conservation , m1 v = m2 2v or m1 = 2 m2 .............(1)
If both nuclei has same density ρ , r1 and r2 are radius of respective nuclei, then eqn.(1) is written as
(4/3)π r13 ρ = 2 (4/3) π r23 ρ ......................(2)
Hence from eqn.(2), we get , ratio of the sizes of nuclei = 21/3 : 1
