If radius of the $^{27}_{13}Al$ nucleus is taken to be $R_{Al}$, then the radius of $^{125}_{53}Te$ nucleus is nearly
${\left( {\frac{{53}}{{13}}} \right)^{\frac{1}{3}}}{R_{Al}}$
$\frac{5}{3}{R_{Al}}$
$\;\frac{3}{5}{R_{Al}}$
$\;{\left( {\frac{{13}}{{53}}} \right)^{\frac{1}{3}}}{R_{Al}}$

What is the nucleus of an atom ?
An alpha nucleus of energy $\frac{1}{2}m{v^2}$ bombards a heavy nuclear target of charge $Ze$. Then the distance of closest approach for the alpha nucleus will be proportional to
