The energy released by the fission of one uranium atom is 200 MeV. The number of fission per second required to prodice 6.4W power is

A

`2xx10^(11)`

B

`10^(11)`

C

`10^(10)`

D

`2xx10^(10)`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Let there is n number of fission per second produces a power of 6.4 W, then
`nxx200x10^(6) xx16x10^(-19) Js^(-1) =6.4Js^(-1)`
`therefore n=(6.4)/( 200xx10^(-13) xx1.6)=(4)/(2xx10^(-11))=2xx10^(11)`
