Draw a graph showing the variation of potential energy of a pair of nucleons as a function of their separation. Indicate the region in which the nuclear force is (a) attractive and (b) repulsive.
Marking-scheme solution
Repulsive nuclear force for \(\displaystyle r<r_{0}\)
Attractive force for \(\displaystyle r>r_{0}\)
