The mass defect in a particular nuclear ...

The mass defect in a particular nuclear reaction is `0.3` grams. The amont of energy liberated in kilowatt hours is.
(Velocity of light `= 3 xx 10^8 m//s`).

A

`1.5xx10^(6)`

B

`2.5xx10^(6)`

C

`3xx10^(6)`

D

`7.5xx10^(6)`

Text Solution

Verified by Experts

The correct Answer is:
A
Potential difference, `V=(hc)/(elamda)`
`=(6.6xx10^(-34)xx3xx10^(8))/(1.6xx10^(-19)xx2xx10^(-10))=6200V`
