The ratio of radii of two nuclei having atomic mass numbers 27 and 8 respectively, will be:

$\frac{R_1}{R_2}=\frac{3}{2}$ $\frac{R_1}{R_2}=\frac{4}{2}$ $\frac{R_1}{R_2}=\frac{6}{4}$ $\frac{R_1}{R_2}=\frac{\sqrt{3}}{2}$

$\frac{R_1}{R_2}=\frac{3}{2}$

The correct answer is Option (1) → $\frac{R_1}{R_2}=\frac{3}{2}$
