Question

Assume that the nuclear binding energy per nucleon `(B//A)` versus mass number (A) is as shown in figure. Use this plot to choose the correct choice(s) given below.
(a) Fusion of two nuclei with mass numbers, lying in the range of `1ltAlt50` will release energy.
Fusion of two nuclei with mass numbers lying in the range of `51ltAlt100` will release energy.
(c) Fission of a nucleus lying in the mass range of `100ltAlt200` will release energy when broken into two equal fragements.
(d) Fission of a nucleus lying in the mass range of `200ltAlt260` will release energy when broken into two equal fragments.

Answer 1

Correct Answer - A::B::D
In fusion, two or more lighter nuclei combine to make a comparatively heavier nucleus. In fission, a heavy nucleus breaks into two or more comparatively lighter nuclei.
Further, energy will be released in a nuclear process if total binding energy increases.
:. The correct options are (b) and (d).
