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

Options

  1. AFusion of two nuclei with mass numbers lying in the range of 1 < A < 50 will release energy
  2. BFusion of two nuclei with mass numbers lying in the range of 51 < A < 100 will release energy
  3. CFission of a nucleus lying in the mass range of 100 < A < 200 will release energy when broken into two equal f
  4. DFission of a nucleus lying in the mass range 200 < A < 260 will release energy when broken into two equal frag

Correct answer

B. Fusion of two nuclei with mass numbers lying in the range of 51 < A < 100 will release energy

Step-by-step solution

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. Futher, energy will be released in a nuclear process if total binding energy increases. correct options are (b) and (d).
