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:
Answer & explanation
Correct answer: option 1
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
