(a) These are strong attractive forces.
(b) These are about 100 times stronger than the Coulomb’s force.
(c) These are short ranged forces(effective upto 10 fm).
(d) They contain a small component of repulsive force which is effective up to a distance of the order of 0.5 fm or 0.5 × 10–15 m or less. This repulsive component prevents the collapse of the nucleus.
(e) These forces are charge independent.
(f) Let d be the range ofthe effectiveness of nuclear forces, then
0.5 fm ≤ d ≤ 10 fm
(g) Let Fpp , Fpn and Fnn denote the magnitude of the nuclear force by a proton on a proton, by a proton on a neutron and by a neutron on a neutron respectively. Then for a separation of 1 fm, Fpp = Fpn = Fnn .
