Draw a plot of potential energy of a pair of nucleons as a function of their separations. Mark the regions where the nuclear force is (i) attractive and (ii) repulsive. Write any two characteristic features of nuclear forces.
For r > OB, force is repulsive.
For r > OB, force is attractive.
Nuclear forces are
(i) very strong,
(ii)charge independent,
(iii)show saturation, and
(iv)spin dependent.
