Question: Q. 2. 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
U [OD South 2016]
Nuclear force is saturated, or short ranged
[Any one]
The final system is more tightly bound when heavy nucleus undergoes nuclear fission. Hence, there is a release of energy.
