In a typical unclear reaction, e.g.
`""_(1)^(2)H+""_(1)^(2)H to ""_(2)^(3)He + n +3.27 Me V`,
although number of nucleons is conserved is conserved, yet energy is released. How ? Explain.
(b) Show that nuclear density in a given nucleus is independent of mass number A.

(a) In a nuclear reaction ""_(2)^(3)He +""_(2)^(3)He to ""_(2)^(4)He+""_(1)^(1)H +""_(1)^(1)H +12.86 MeV, though the number of nucleons is conserved on both sides of the reaction, yet the energy is released. How? Explain. (b) Draw a plot of potential energy between a pair of nucleons as a function of their separation. Mark the regions where potential energy is (i) positive and (ii) negative.
