Nuclei - Result Question 34
35. The binding energy of deuteron is $2.2 MeV$ and that of $ _2^{4} He$ is $28 MeV$. If two deuterons are fused to form one $ _2^{4} He$, then the energy released is
(a) $23.6 MeV$
(b) $19.2 MeV$
(c) $30.2 MeV$
(d) $25.8 MeV$

Answer:
Correct Answer: 35. (a)
Solution:
- (a) $ _1 D^{2} \longrightarrow _2 He^{4}$
Energy released $=28-2 \times 2.2=23.6 MeV$
Binding energy is energy released on formation of Nucleus
