Nucleus: Composition, Size & Nuclear Force

The volume occupied by an atom is greater than the volume of the nucleus by a factor of about

Show answer and solution

Answer: (d)

Atomic radius $\sim 10^{-10}$ m, nuclear radius $\sim 10^{-15}$ m.
Radius ratio $\sim 10^{5}$ , and $V \propto r^3$ .
Volume ratio $\sim (10^{5})^3 = 10^{15}$ .
So the answer is (d) $10^{15}$ .
