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

Options

  1. AFusion of two nuclei with mass numbers lying in the range of 1<A<501 < A < 50 will release energy
  2. BFusion of two nuclei with mass numbers lying in the range of 51<A<10051 < A < 100 will release energy
  3. CFission of a nucleus lying in the mass range of 100<A<200100 < A < 200 will release energy when broken into two equal fragments
  4. DFission of a nucleus lying in the mass range 200<A<260200 < A < 260 will release energy when broken into two equal fragments

Correct answer

B. Fusion of two nuclei with mass numbers lying in the range of 51<A<10051 < 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. ∴\therefore correct options are (b) and (d).
