STANDARD Physics Binding Energy Multiple Correct Question

Type: Multiple Correct-conceptual-Hard

Mass numbers of the elements A, B, C and D are 30, 60, 90 and 120 respectively. The specific binding energy of them are 5 MeV, 8.5 MeV, 8MeV and 7 MeV respectively. Then, in which of the following reaction/s energy is released? (i) D → 2B (ii) C → B + A (iii) B → 2A

A

(i) D → 2B

B

(ii) C → B + A

C

(iii) B → 2A

Correct Answer

Option A

Detailed Explanation

Energy is released in a nuclear reaction if the products have a higher binding energy per nucleon than the reactants. In reaction (i), the binding energy per nucleon increases from 7 MeV to 8.5 MeV, releasing energy.
