A) \[19.2\,\,MeV\]
B) \[23.6\,\,MeV\]
C) \[26.9\,\,MeV\]
D) \[13.9\,\,MeV\]
Correct Answer: B
Solution :
Total binding energy of \[_{1}{{H}^{2}}=2\times 1.1=2.2\,\,MeV\] Total binding energy of two deuterium nuclei\[=2\times 2.2=4.4\,\,MeV\] Total binding energy of \[_{2}H{{e}^{4}}=4\times 7=28\,\,MeV\] Energy released in fusion\[=28-4.4\] \[=23.6\,\,MeV\]
