A

`1.492 xx 10^(-10) J`

B

`1.492 xx 10^(-7) J`

C

`1.492 xx 10^(-13) J`

D

`6.023 xx 10^(23) J`

Text Solution

Verified by Experts

The correct Answer is:
A
`1 u = 1.66 xx 10^(-24)`g
`= 1.66 xx 10^(-27)` kg
`= 1.66 xx 10^(-27) xx (3 xx 10^(8) )^(2) kg m^(2) s^(-2) (because E = mc^(2))`
`= 1.494 xx 10^(-10) J`
