Question

A certain mass of Hydrogen is changed to Helium by the process of fusion. The mass defect in fusion reaction is $0.02866u$. The energy liberated per $u$ is (given $1u=931MeV$)

• A. $2.67MeV$
• B. $26.7MeV$
• C. $6.675MeV$
• D. $13.35MeV$

Answer 1

The correct option is C $6.675MeV$

$\frac{0.02866\times 931}{4}MeV=\frac{26.7}{4}MeV$$=6.675MeV$
