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. 6.675 MeV
B. 13.35 MeV
C. 2.67 MeV
D. 26.7MeV

Explanation

As `""_(1)^(2)H+""_(1)^(2)Hrarr""_(2)^(4)He`
Here, `DeltaM=0.02866u`
`therefore" The energy liberated per u is"`
`=(DeltaMxx931)/(4)MeV`
`=(0.02866xx931)/(4)MeV=(26.7)/(4)MeV=6.675MeV`
