Answer:

Correct Answer: 9. (a)

Solution:

(a) $V \propto r^{3} \Rightarrow V _{\text{atom }}=\frac{r _{\text{atom }}^{3}}{r _{\text{nuclers }}^{3}} \times V _{\text{nucleus }}$

But $\frac{r _{\text{nucleus }}}{r _{\text{atom }}}=(\frac{1}{10^{5}})^{3}$

Hence, $V _{\text{atom }}=10^{15} \times V _{\text{nucleus }}$
