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)`

A

2.67 MeV

B

26.7 MeV

C

6.675 MeV

D

13.5 MeV

Text Solution

Verified by Experts

The correct Answer is:
C
The energy equivalent of 1 u = 931 MeV and for helium A = 4.
`thereore` Energy liberated per atomic mass unit (u) of helium
`= ("Mass defect" (Delta m) xx c^(2))/("Number of nucleons (A)")`
`= (0.02866 xx 931)/(4) ~~ (26.7)/(4) = 6.675` MeV
