Question 551: Atoms & Nuclei

Question

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

Accepted Answer

Radius of nuclei with mass number A varies as
$$R = {R_0}{A^{1/3}}$$
$${{{R_1}} \over {{R_2}}} = {\left( {{{125} \over {64}}} \right)^{1/3}} = {5 \over 4} = 5:4$$
