The mass number of $He$ is $4$ and the mass number of $S$ is $32$. How many times is the radius of the $S$ nucleus compared to the radius of the $He$ nucleus?

The ratio of the nuclear radii of elements with mass numbers $216$ and $125$ is

What is the mass number of a nucleus having a radius equal to $\frac{1}{3}$ of that of ${}^{189}\text{Os}$?

Obtain approximately the ratio of the nuclear radii of the gold isotope $^{197}_{79}Au$ and the silver isotope $^{107}_{47}Ag$.
