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: A. Fusion of two nuclei with mass numbers lying in the range of `1 lt A lt 50` will release energyB. Fusion of two nuclei with mass numbers lying in the range of `51 lt A lt 100` will release energyC. Fission of a nucleus lying in the the mass range of `100 lt A lt 200` will release energy when broken into two equal fragmentsD. Fission of a nucleus lying in the mass range of `200 lt A lt 260` will release energy when broken into two equal fragments |

Answer» Correct Answer - B::D (A) for `1 lt A lt 50`, on fusion mass number for compound nucleus is less than `100` `implies` Binding energy nucleon remains same `implies` No energy is released (B) For `51 lt A lt 100` on fusion mass number for compound nucleus is between `100` & `200` `implies` binding energy per nucleon increases `implies` Energy is released. (C) For `100 lt A lt 200`, on fission, the mass number of product nuclei will be between `50` & `100` `implies` Binding energy per nucleon decreases `implies` No energy is released (D) For `200 lt A lt 260`, on fission, the mass number of product nuclei will be between `100` & `130` `implies` Binding energy per nucleon increases `implies` Energy is released. |
