Q. Two nucleons are at a separation of one $fermi$. Protons have a charge of + $1.6\ \times \ 10^{- 19}$ C. The net nuclear force between them is $F_{1}$, if both are neutrons ,$F_{2}\ $if both are protons and $F_{3}\ $if one is proton and the other is neutron. Then
A) $F_{1} = F_{2} > F_{3}$
B) $F_{1} = F_{2} = F_{3}$
C) $F_{1} < F_{2} < F_{3}$
D) $F_{1} > F_{2} > F_{3}$
Explanation
(b) Nuclear forces are charge independent so,
$\ \ \ \ \ \ \ \ \ \ F_{1} = F_{2} = F_{3}.$
