If in nuclear fission, a piece of uranium of mass 0.5g is lost, the energy obtained (in kWh) is `n xx 10^(7)`. Find the value of n.

Text Solution

Verified by Experts

The correct Answer is:
1.25
`E=Deltamc^(2)`
`=0.5xx10^(-3)xx(3xx10^(8))^(2)`
`=4.5xx10^(13)`
`E=(4.5xx10^(13))/(3.6xx10^(6))`
`=1.25xx10^(7) kWh`
