Assume that the nuclear binding energy per nucleus` (B//A)` versus mass number `(A)` is as shown in the figure Use this plot to choose the correct (s) choice given below

Options

A. fusion of a two nuclei with mass number lying in the range of `1lt A lt 50` will release energy
B. fusion of a two nuclei with mass number lying in the range of `51 lt A lt 100` will release energy
C. fusion of a nucleus lying in the mass range of `100 lt A lt 200` will release energy than broken into two equal fragments.
D. fusion of a nucleus lying in the mass range of `200 lt A lt 200` will release energy than broken into two equal fragments.

Answer

B, D

Explanation

Energy is released only when final B.E. gtInitial B.E. (as binding energy stands for loss of energy during fission of fusion). Choices (b) and (d) are correct.
