Two protons are at $$10$$ A distance from each other. The nuclear force and electrostatic force between them is $$F_n$$ and $$F_e$$ respectively. Thus:
C
$$F_n$$ is only a bit more than $$F_{e^-}$$
Correct option is B. $$F_e > > F_n$$
Nuclear forces are the strongest forces in the universe, the nucleus of an atom remains stable because of the presence of nuclear forces between the protons.
However, nuclear forces are extremely short range and is experienced by the nucleons only in the femtometer ($$10^{-15}$$) range. At the angstrom range nuclear forces are negligible compared to electrostatic force.
