Assume that the nuclear binding energy per uncleon `(B//A)` versus mass number `(A)` is as shwon in Fig. Use this plot to choose the correct choice `(s)` given below:

Options

A. Fusion of two nuclei with mass number lying is the range of `1 lt A lt 50` will release energy
B. Fusion of two nuclei with mass number lying in the range of `51 lt A lt 100` will release energy
C. Fission of a nucleus lying in the mass range of `100 lt A lt 200` will release energy when broken into equal fragments.
D. Fission of a nucleus lying in the mass range of `200 lt A lt 260` will release energy when broken into equal fragments.

Answer

B, D

Explanation

In fussion two or more lighter nuclei combined to make a comparatively heavier nucleus. In fission a heavy nucleus breaks into two or more lighter nuclei. Further energy will be released in nucleus process if total binding energy increases. Hence B,D are correct
