Calculate the energy in MeV equivalent to the rest mass of an electron . Given that the rest mass of an electron , `m=9.1 xx 10^(-31) kg`, `1MeV = 1.6 xx 10^(-13) J` and speed of light , `c= 3 xx 10 ^(8) ms ^(-1)`.

Explanation

To calculate the energy equivalent to the rest mass of an electron in MeV, we will follow these steps:

### Step 1: Use the mass-energy equivalence formula
The energy \( E \) can be calculated using the formula:
\[ E = mc^2 \]
where:
