Nucleus: Composition, Size & Nuclear Force

A nucleus of mass number 189 splits into two nuclei having mass number 125 and 64. The ratio of radius of two daughter nuclei respectively is

Show answer and solution

Answer: (c)

$R \propto A^{1/3}$ , so $\frac{R_1}{R_2} = \left(\frac{125}{64}\right)^{1/3}$ .
$= \frac{5}{4}$
So the answer is (c) $5 : 4$ .
