In a thermonuclear reaction, the total initial mass is 5.02 x 1027kg and the total final mass is 5.01 x 1027kg. The energy released in the process is
[c = 3.0 x 108 ms-1]

A.

9.0 x 10-13J

B.

9.0 x 10-12J

C.

9.0 x 10-11J

D.

9.0 x 10-10J

Correct answer is A

In thermonuclear reactions,
Energy = ∆mC2
∆m = Change in Mass
C = Speed of light
∴ 5.02 x 10-27 - 5.01 x 10-27 x [3 x 108]2
0.01 x 10-27 x 9 x 1016
E = 9.0 x 10-13J
