The binding energy of deuteron is 2.2 MeV and that of 2He4 is 28 MeV. If two deuterons are fused to form one 2He4, then the energy released is
-
- 23.6 MeV
- 19.2 MeV
- 30.2 MeV
- 25.8 MeV
Correct Option: A
1D2 → 2He4
Energy released = 28 – 2 × 2.2 = 23.6 MeV
(Binding energy is energy released on formation of Nucleus)
