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 $1 u = 931 MeV$ )NEET 2013 (All India)

Options:

Answer:

Solution:

Here, $Δ m = 0.02866 U$ $∴ Energy liberated = \frac{0.02866 \times 931}{4} = \frac{26.7}{4} MeV = 6.675 MeV$
