Statement I: Volume of the nucleus is proportional to a where A is mass number.

Statement II: Density of nucleus is independent of mass number A.

In the light of the: above statements, choose the correct answer from the options given below:

Both Statement I and Statement II are true

The correct answer is Option (1) → Both Statement I and Statement II are true

Radius of nucleus $R=R_0 A^{1 / 3}$

$\Rightarrow$ Volume $\propto R^3$

$\Rightarrow V \propto A$

Density of nucleus

$(\rho)=\frac{m}{\text { Volume }}=\frac{M A}{K A}=\frac{M}{K}=$ constant
