The change in mass of fuel during a nuclear reaction is 2.0 x 10-27 kg. Calculate the amount of energy released. (Speed of light = 2.0 x 108ms-1)
A
1.8 x 10-10J
B
9.0 x 10-11J
C
6.0 x 10-19J
D
1.2 x 10-45J
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Q = \(\Delta MC^2\)
= 2 x 10-27(3 x 10)2
= 1.8 x 10-10J
