If radius of the $^{27}_{13}Al$ nucleus is taken to be $R_{Al}$, then the radius of $^{125}_{53}Te$ nucleus is nearly
${\left( {\frac{{53}}{{13}}} \right)^{\frac{1}{3}}}{R_{Al}}$
$\frac{5}{3}{R_{Al}}$
$\;\frac{3}{5}{R_{Al}}$
$\;{\left( {\frac{{13}}{{53}}} \right)^{\frac{1}{3}}}{R_{Al}}$
An unstable heavy nucleus at rest breaks into two nuclei which move away with velocities in the ratio of $8:27$. The ratio of the radii of the nuclei (assumed to be spherical ) is
