The amount of energy approximately be released if all the atoms of 1kg of Deuterium could undergo fusion is (Assume in the fusion of Deuterium, 0.7% of mass is converted into energy)
 

a
8 x1023MeV
b
9 x1013 J
c
1.75 x 108 Kwh
d
6 x 1027 Cal

detailed solution

Correct option is C

0.7% mass converted into energy then according to E = mc2 0.7 x1 x9 x 1016100J 0.7 x1 x9 x 1016100 x3.6 x 105 Kwh=74 x 108Kwh
