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

$A$ nucleus disintegrates into two nuclear parts,in such a way that the ratio of their nuclear radii is $1: 2^{1/3}$. Their respective speeds have a ratio of $n: 1$. The value of $n$ is $.....$.

$A$ reaction between a proton and $_8^{18}O$ that produces $_9^{18}F$ must also liberate:

The charge density $P$ in a nucleus varies with distance $r$ from the centre of the nucleus according to the curve in the figure. Which of the following graphs correctly represents this variation?

$A$ nucleus breaks into two nuclear parts,which have their velocity ratio $2:1$. The ratio of their nuclear radii will be

State the dimension of the nucleus from the Rutherford experiment.
