Two nuclei have their mass numbers in the ratio of `1:3`. The ratio of their nuclear densities would beA. `(3)^(1//3):1`B. `1:1`C. `1:3`D. `3:1`

Answer» Correct Answer - B
`R=R_(0).A^(1//3)`
So nuclear density `=(A.m)/(v)`
m = mass of each nucleon, A = mass number
`=(3m)/(4piR_(0)^(3))=" independent of A."`
