If the radius of the $_{13}^{27}Al$ nucleus is estimated to be $3.6 \, \text{Fermi}$, then the radius of the $_{52}^{125}Te$ nucleus will be nearly .......... $\text{Fermi}$.

Two deuterons are moving towards each other with the same speed. If the distance of closest approach is $2 \, fm$,what should be their initial kinetic energy in $MeV$?

$A$ nucleus at rest splits into two nuclear parts having radii in the ratio $1:2$. Their velocities are in the ratio: (in $:1$)

$A$ heavy nucleus is unstable for any value of $\frac{N}{P}$ because

Consider the following two statements, $A$ and $B$ and identify the correct answer given below:
$A$. Nuclear density is same for all nuclei.
$B$. Radius of the nucleus $R$ and its mass number $A$ are related as $\sqrt{A} \propto R^{1 / 6}$.

If a nucleus $D$ at rest breaks up into two fragments $A$ and $C$ which fly off with velocities in the ratio $8 : 1$,then the ratio of the radii of the fragments is
