Question
As the mass number A increases, the binding energy per nucleon in a nucleus:
✓

Answer

  1.  Varies in a way that depends on the actual value of A.
Explanation:
Binding energy per nucleon in a nucleus first increases with increasing mass number (A) and reaches a maximum of 8.7MeV for A (50 - 80). Then, again it slowly starts decreasing with the increase in A and drops to the value of 7.5MeV.
