उत्तर
Plot of binding energy per nucleon as the function of mass number A is given as below:
Following are the two conclusions that can be drawn regarding the nature of the nuclear force:
(i) The force is attractive and strong enough to produce a binding energy of few MeV per nucleon.
(ii) The constancy of the binding energy in the range 30
