The ratio of mass densities of nuclei of $^{40}Ca$ and $^{16}O$ is close to
$0.1$
$5$
$2$
$1$
Mass densities of all nuclei are same so their ratio is $1$.
The volume occupied by an atom is greater than the volume of the nucleus by a factor of about
Two protons exerts a nuclear force on each other, the distance between them is
Nuclear forces are
Two nucleons are at a separation of $1 \times {10^{ – 15}}m$. The net force between them is ${F_1}$, if both are neutrons, ${F_2}$ if both are protons and ${F_3}$ if one is a proton and other is a neutron. In such a case
If a ${H_2}$ nucleus is completely converted into energy, the energy produced will be around……….$MeV$
