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

26.7 MeV

B

6.675 MeV

C

13.35 MeV

D

2.67 MeV

Text Solution

Verified by Experts

Mass defect in fusion
`Deltam=0.02866`u
Energy liberates
`E=0.02866 xx 931 MeV= 26.7 MeV`
4 u liberate 26.7 MeV of energy
1u liberate `=(26.7)/4 MeV = 6.675` MeV
