$F_{\mathrm{pp}}, F_{\mathrm{nn}}$ and $F_{\mathrm{np}}$ are the nuclear forces between proton-proton,…

$F_{\mathrm{pp}}, F_{\mathrm{nn}}$ and $F_{\mathrm{np}}$ are the nuclear forces between proton-proton, neutron-neutron and neutron-proton respectively. Then relation between them is
  1. $F_{\mathrm{pp}}=F_{\mathrm{nn}} \neq F_{\mathrm{np}}$
  2. $F_{\mathrm{pp}} \neq F_{\mathrm{nn}}=F_{\mathrm{np}}$
  3. $F_{\mathrm{pp}}=F_{\mathrm{nn}}=F_{\mathrm{np}}$
  4. $F_{\mathrm{pp}} \neq F_{\mathrm{nn}} \neq F_{\mathrm{np}}$

Solution

Nuclear force between two particles is independent of charges of particle. $\Rightarrow \quad F_{p p}=F_{n n}=F_{n p}$
