Solution

The correct option is A $E_{n} > E_{e}$
In any atom, protons and neutrons are packed together in a very small space in the nucleus.
There must be some force of attraction between these particles to maintain the existence of nucleus.
The columbic force of attraction is not enough to hold many particles in such a small space, as the repulsion force between protons would render the nucleus highly unstable and tend to disintegration.
Hence, the force of attraction between nucleons which is stronger than the repulsive force between protons is called as nuclear forces.
Nuclear forces operate within a small distance around 0.10 fermi only.
$E_{n} > E_{e}$ (nuclear forces $>$ coulombic forces)
