1 kg of U235 undergoes fission process. If energy released per event is 200 MeV, then total energy released is 

a
5.12×1024MeV
b
6.02×1023MeV
c
5.12×1026MeV
d
6.02×1026MeV

detailed solution

Correct option is C

Number of nuclei in 1 kg of  235U is N=NA235×(1×103)=6.023×1023×103235=2.56×1024∴ Total energy released 0=N×200MeV=5.12×1026MeV
