The ratio of the nuclear densities of $^{27}$Al and $^{125}$Te is
Answer: (B) $1 : 1$
Concept. $R = R_0A^{1/3}$, so the volume is proportional to $A$, as is the mass. Nuclear density is the same for all nuclei.
Step 1. Ratio. $\rho \propto \dfrac{A}{A}$, so the ratio is $1 : 1$.
Answer. $1 : 1$ (Option B).
