Write two characteristic properties of nuclear force.
(b)
Draw a plot of potential energy of a pair of nucleons as a function of their separation. Write two important conclusions that can be drawn from the plot.
Marking-scheme solution
(a) Properties of nuclear forces :
(i) The nuclear force is much stronger than the Coulomb force acting between charges or the gravitational forces between their masses.
(ii) The nuclear force between two nucleons falls rapidly to zero as their distance becomes more than a few femtometres.
(iii) The nuclear force between neutron- neutron, proton- neutron
