Radius of the nucleus = 1.33 x 10-11 x \(A^{\frac{1}{3}}\)m
Density of nucleus = \(\frac{mass}{volume}\)
= \(\frac{A\times1.66\times10^{-27}kg}{\frac{4}{3}\times\pi\times(1.33\times10^{-11})^3}kg/m^3\)
= Constant
\(\therefore\) The density of nucleus is constant, independent of the element under consideration.
