Nucleus: Composition, Size & Nuclear Force

If the nuclear force between two protons, two neutrons and between proton and neutron is denoted by $F_{pp}, F_{nn}$ and $F_{pn}$ respectively, then

Show answer and solution

Answer: (c)

The nuclear force is charge independent.
So the nuclear force is the same for p-p, n-n and p-n pairs at the same separation.
So the answer is (c) $F_{pp} = F_{nn} = F_{pn}$ .
