Question

From the relation \(R= R_0A^{1/2}\) where R₀ is a constant and A is the mass number of a nucleus, show that the nuclear matter density is nearly constant. (i.e. independent of A).

Answer 1

Let us find the density of the nucleus of an atom, whose mass number is A.
The mass of the nucleus of the atom of mass number A

∴ Nuclear matter density is independent of A.
