A certain mass of Hydrogen is changed 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)
A
13.35 MeV
B
2.67 MeV
C
26.7 MeV
D
6.675 MeV
Detailed Solution
The helium formed has mass 4 u, so energy released per u $= \left(\frac{0.02866}{4}\right)(931\ MeV) = 6.675$ MeV
