Plot a graph showing the variation of binding energy per nucleon as a function of mass number. Which property of nuclear force explains the approximate constancy of binding energy in the range 30 < A < 170? How does one explain the release of energy in both the processes of nuclear fission and fusion from the graph?

Nuclear force is Saturated, or short ranged The final system is more tightly bound when heavy nucleus undergoes nuclear fission. Hence, there is a release of energy. The final system is more tightly bound when light nuclei undergoes nuclear fusion. Hence, there is a releases of energy.
Alternate Answer
There is an increase in BE/nucleon both during:
- Nuclear fission of heavy nuclei and,
- Nuclear fussion of light nuclei Nuclear.
