Nuclear force is
1 short range and change dependent
2 short range and charge independent
3 long range and charge dependent
4 long range and charge independent
Explanation:
B The nuclear force is short range near about $10^{-15} \mathrm{~m}$ or 1 fermi can be both attractive and repulsive in nature. Nuclear force is independent of charge.

The range of weak nuclear force is
1 $10^{-10} \mathrm{~m}$
2 $10^{-15} \mathrm{~m}$
3 $10^{-20} \mathrm{~m}$
4 $10^{10} \mathrm{~m}$
Explanation:
B For the weak nuclear force are in the range of $10^{-17} \mathrm{~m}$ to $10^{-15} \mathrm{~m}$. So weak nuclear force is in the range of $10^{-15} \mathrm{~m}$.

A radioactive nucleus emits a beta particle. The parent and daughter nuclei are
1 Isotopes
2 Isotones
3 Isomers
4 Isobars
Explanation:
D The parent and daughter nuclei are isobars because the emission of $\beta$-particle mass number never be changed.

The correct statement of the following is
1 The Q-value of a nuclear process is the difference between final and initial kinetic energies.
2 The nuclear mass is always higher than the total mass of its constituents
3 Nuclides with same number of neutrons in the nucleus are known as isotopes,
4 In nuclear fusion, a heavy nucleus breaks into two smaller fragments.
Explanation:
A The Q-valve of the reaction is defined as the difference between the sum of the masses of the initial reactants and the sum of the masses of the final product. It is measure in $\mathrm{MeV}$. It is measure of amount of energy released by that reaction.
B The nuclear force is short range near about $10^{-15} \mathrm{~m}$ or 1 fermi can be both attractive and repulsive in nature. Nuclear force is independent of charge.
