The energy in MeV is released due to tra...

The energy in `MeV` is released due to transformation of `1 kg` mass completely into energy `(c = 3 xx 10^8 m//s)`.

A

`7.625 xx 10 Mev`

B

`10.5 xx 10^29 MeV`

C

`2.8 xx 10^-28 MeV`

D

`5.625 xx 10^29 MeV`

Text Solution

Verified by Experts

The correct Answer is:
D

(d) `E = Delta mc^2 = 1 xx (3 xx 10^8) = 9 xx 10^10 J`
`rArr E = (9 xx 10^16)/(1.6 xx 10^-19) = 5.625 xx 10^35 eV`
=`5.625 xx 10^29 MeV`.
