A certain mass of hydrogen is changes to helium by the process of fusion. The mass defect in fusion reaction is `0.02866 u`. The energy liberated per `u` is (given `1 u = 931 MeV)`

Options

A. 26.7 MeV
B. 6.675 Me V
C. 13.35 MeV
D. 2.67 MeV

Answer

B

Explanation

Mass defect Dm = 0.02866 a.m.u.
Energy = 0.02866 `xx 931 = 26.7` Me V
As `""_(1) H^(2) + ""_(1) H^(2) to ""_(2) He^(4)`
Energy liberated per a.m.u = 13.35/2 Me V = 6.675 Me V
