Question
The binding energy per nucleon of deuteron 
and helium nucleus 
is 1.1 MeV and 7 MeV respectively. If two deuteron nuclei react to form a single helium nucleus, then the energy released is
and helium nucleus is 1.1 MeV and 7 MeV respectively. If two deuteron nuclei react to form a single helium nucleus, then the energy released isOptions
A.13.9 MeV
B.26.9 MeV
C.23.6 MeV
D.19.2 MeV
Solution
Energy released = total binding energy of product - total binding energy of reactants
⇒ 28 - (2 × 2.2) = 28 - 4.4 = 236 MeV.
⇒ 28 - (2 × 2.2) = 28 - 4.4 = 236 MeV.
