The power obtained in a reactor using U^...

The power obtained in a reactor using `U^(235)` disintergration is `1000kW`. The mass decay of `U^(235)` per hour is

A

1 microgram

B

10 microgram

C

20 microgram

D

40 microgram

Text Solution

Verified by Experts

The correct Answer is:
D
Energy (E) `= mc^(2)`
`m= (1000 xx 10^(3) xx 3600)/((3 xx 10^(8))^(2))= 40` micro gram.
