A) nuclear force is greater than gravitational force
B) gravitational force is greater than nuclear force
C) electromagnetic force is lesser than gravitational force
D) nuclear force is greater than electromagnetic force
Correct Answer: A

If the distance between nucleons is of the order of 10 cm, then nuclear force is much greater titan gravitational and electromagnetic forces. Nuclear forces are primarily the forces of attraction and are responsible in binding of nucleons in a nucleus.
