A certain mass of hydrogen is changed to...

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 MeV

B

26.7 MeV

C

6.675 MeV

D

13.35 MeV

Text Solution

Verified by Experts

The correct Answer is:
C
Here, `Deltam=0.02866U`
`therefore ` Energy liberated
`=(0.02866xx931)/(4)=(26.7)/(4)MeV=6.675MeV`
