The nuclear radius is given by $R=r_0 A^{1 / 3}$, where $r_0$ is constant and $A$ is the atomic mass number. Then, the nuclear mass density of $U^{238}$ is
twice that of $\operatorname{Sn}^{119}$
thrice that of $Sn ^{119}$
same as that of $Sn ^{119}$
half that of $Sn ^{119}$
$1 a.m.u.$ is equivalent to
Assume that protons and neutrons have equal masses. Mass of a nucleon is $1.6 \times 10^{-27}\,kg$ and radius of nucleus is $1.5 \times 10^{-15} A ^{1 / 3}\,m$. The approximate ratio of the nuclear density and water density is $n \times 10^{13}$. The value of $n$ is $.................$
What kind of a force does neutron-neutron ?
The ratio of radii of nuclei $_{13}A{l^{27}}$ and $_{52}{X^A}$ is $3 : 5$. The number of neutrons in the nuclei of $X$ will be
The nuclei of which one of the following pairs of nuclei are isotones
