For effective nuclear forces,the distance should be

The maximum potential energy due to electrostatic repulsion between two hydrogen nuclei is nearly (radius of the nucleus $= 1.1 \ Fermi$). $\left[ \frac{1}{4 \pi \epsilon_0} = 9 \times 10^9 \ N \ m^2 \ C^{-2} \right]$ (in $MeV$)

Which of the following is not made by quarks?

If the radius of $_{13}^{27}Al$ is $3.6 \ fm$,then the radius of the $_{52}^{125}Te$ nucleus will be ........ $fm$.

The mass number of $He$ is $4$ and that for sulphur is $32$. The radius of the sulphur nucleus is larger than that of the helium nucleus by a factor of:

Nuclear reactions are given as:
$(i) \, \square (n, p) {_{15}}P^{32}$
$(ii) \, \square (p, \alpha) {_{8}}O^{16}$
$(iii) \, {_{7}}N^{14} (\square, p) {_{6}}C^{14}$
The missing particles or nuclides (in box $\square$) in these reactions are respectively:
