One amu is equivalent of 931meV energy. The rest mass of electron is `9.1xx10^(-31)kg`. The mass equivalent energy is (Here `1amu=1.67xx10^(-27)kg`)

A

`2.5073MeV`

B

`0.693 MeV`

C

`4.0093MeV`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
(a) The mass off electron `=(9.1xx10^(-31))/(1.67xx10^(-27))` (amu)
`:.E=(9.1xx10^(-31))/(1.67xx10^(-27))xx931` MeV `=2.5073MeV`
