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

`2.67` Me V

B

`26.7` Me V

C

`6.675` Me V

D

`13.35` Me V

Text Solution

Verified by Experts

The correct Answer is:
C
`4H_(1)^(1)to2He^(4)+2beta^(+)+2y`
Here, `Deltam=0.02866u`
:. Energy liberated `=Deltamxx931MeV`.
`=0.02866xx931=26.7MeV`
:. Energy liberated per fusion (i.e.,n=4) `=(26.7)/(4)MeV`
=6.675MeV
