Question

$F_{pp},F_{nn}$ and $F_{np}$ are the nuclear forces between proton-proton, neutron-neutron and neutron-proton respectively. Then relation between them is

• A. $F_{pp}=F_{nn}\ne F_{np}$
• B. $F_{pp}\ne F_{nn}=F_{np}$
• C. $F_{pp}=F_{nn}=F_{np}$
• D. $F_{pp}\ne F_{nn}\ne F_{np}$

Answer 1

Answer: (C)

$F_{pp}=F_{nn}=F_{np}$

Nuclear force between two particles is independent of charges of particles.
$\Rightarrow F_{pp}=F_{nn}=F_{np}$
