The energy in MeV is released due to transformation of 1 kg mass completely into energy (c = 3 × 108m/s)-
A
7.625 × 10 MeV
B
10.5 × 1029 MeV
C
2.8 × 10–28 MeV
D
5.625 × 1029 MeV
Answer
5.625 × 1029 MeV
Explanation
Solution
E = mc2 = (1) (3 × 108)2
E = 9 × 1016 J = 1.6×10−139×1016MeV
= 1.69×1029MeV
= 5.625 × 1029 MeV
