Q47 / 97 · NTA Abhyas (JEE Main) 2020 · Physics · Nuclear Physics
Assume that the nuclear binding energy per nucleon () versus mass number () is as shown in the figure. Use this plot to choose the correct choice given below.
- AFusion of two nuclei with mass numbers lying in the range of 1 < A < 50 will release energy.
- BFusion of two nuclei with mass numbers lying in the range of 51 < A < 100 will consume energy.
- CFission of a nucleus lying in the mass range of 100 < A < 200 will release energy when broken into two equal fragments.
- Correct answerDFission of a nucleus lying in the mass range of 200 < A < 260 will release energy when broken into two equal fragments.
Solution
In fusion, two or more lighter nuclei combine to make a comparatively heavier nucleus.
In fission, a heavy nucleus breaks into more than one comparatively lighter nucleus.
Further, energy will be released in a nuclear process if total binding energy increases.
Therefore Correct option is that the fission of a nucleus lying in the mass range of 200 < A < 260 will release energy when broken into two equal fragments.

Therefore Correct option is that the fission of a nucleus lying in the mass range of 200 < A < 260 will release energy when broken into two equal fragments.
Hence, the correct answer is option: 'D'.
