Two nuclei have their mass numbers in the ratio of $1 : 3.$ The ratio of their nuclear densities would be
${\left( 3 \right)^{\frac{1}{3}}}:1$
$1:1$
$1:3$
$3:1$
If the nucleus ${}_{13}^{27}Al$ has a nuclear radius of about $3.6\,\, fm,$ then ${ }_{32}^{125} Te$ would have its radius approximately as .......$fm$
Nuclear forces are
Ratio of nuclear radii of ${ }^{135} Cs$ to ${ }^{40} Ca$ is
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:
What percentage of the mass of the nucleus is the mass of the nucleus ?
