Number of fission required in one second to attain a power level of 1 MW in an atom bomb will be:

Answer»

`3.13 XX 10^(16)`
`2.27 xx 10^(15)`
`3.98 xx 10^(16)`
`1.651 xx 10^(17)`

Solution :`E=p xx t=10^(6)J`
Energy/fission=200MeV `=3.2 xx 10^(-11)J`
No. of fission REQUIRED PER set `=(10^(6))/(3.2 xx 10^(-11))`
`=3.13 xx 10^(16)`
