Show that nuclear density is almost constant for nuclei with Z > 10.

उत्तर
Nuclear density `rho = "mass of the nuclei"/"Volume of the nuclei"`
`= "A.m"/(4/3 pi"R"_0^3 "A") = "m"/(4/3 pi"R"_0^3)`
`rho = (1.67 xx 10 - 27)/(4/3 pi xx (1.2 xx 10^-15)^3)`
`= 2.3 xx 10^17`kg m-3
The nuclear density is independent of the mass number A. The nuclear density is almost constant for all the nuclei (Z > 10) irrespective of its size.
