Properties of Nucleus

The masses of nucleus, neutron and proton are $M, m_n$ and $m_p$, respectively. If the nucleus is divided into neutrons and protons, then,

If the nucleus ${}_{13}{}^{27}\mathrm{Al}$ has a nuclear radius of about $3.6 \mathrm{fm}$, then ${}_{52}{}^{125}\mathrm{Te}$ would have its radius approximately equal to,

Two protons are kept at a separation of $50 \stackrel{\circ }{\mathrm{A}}$. If $F_{\mathrm{n}}$ is the nuclear force and $F_{\mathrm{e}}$ is the electrostatic force between them, then,

If ${}_{92}\mathrm{U}^{238}\stackrel{}{\to }{}_z\mathrm{X}^A+{}_2\mathrm{He}^4$, then $Z$ and $A$ will be,

Which of the following pairs of nuclei are isotones?

The mass number of Helium and Sulphur are $4$ and $32$, respectively. The radius of nucleus of Sulphur is how many times greater than the radius of Helium nucleus?

The volume occupied by an atom is greater than the volume of the nucleus by a factor of about,

Two nuclei have their mass numbers in the ratio $1:3$. The ratio of their nuclear densities would be,

The atomic weight of Boron is $10.81$ and it has two isotopes, ${}_5{}^{10}\mathrm{B}$ and ${}_5{}^{11}\mathrm{B}$ in nature. The ratio of the number of atoms in them would be,

A nucleus disintegrates into two nuclear parts having their velocities in the ratio $2:1$. The ratio of their nuclear radii will be,

The stable nucleus that has a radius ${\frac{1}{3}}^{\mathrm{rd}}$ of that of ${\mathrm{Os}}_{76}^{189}$ is,

The mass number of a nucleus is,
