Question

The energy released in the fission of $ 1 \,kg $ of $ _{92}{{U}^{235}} $ is (energy per fission = 200 MeV)

• A. $ 5.1\times {{10}^{26}}eV $
• B. $ 5.1\times {{10}^{26}}J $
• C. $ 8.2\times {{10}^{13}}J $
• D. $ 8.2\times {{10}^{13}}MeV $
• E. $ 5.1\times {{10}^{23}}MeV $

Answer 1

Answer: (C)

Energy released from 1 kg of uranium
$ =\frac{200\times {{10}^{6}}\times 1.6\times {{10}^{-19}}\times 6.023\times {{10}^{26}}}{235} $
$ =8.2\times {{10}^{13}}J $
