For two protons,  the gravitational force is attractive
in nature and the Coulomb force is repulsive The actual values
of these forces between two protons inside a nucleus (distance
between two protons is ~ 10-15 m inside a nucleus) are Fe ~ 230 N,
whereas, FG ~ 1 9 × 10–34 N The (dimensionless) ratio of the two forces shows that electrical
forces are enormously stronger than the gravitational forces
