    Answer:

    Explanation:

    The rest energy of any substance is defined by the Einstein’s mass energy equivalence relation. Thus the rest mass of a electron is 9.11×10^-31 kg. The speed of light is 299,792,458 m/s. Thus multiplying the square of speed of light with the rest mass of electron gives the rest energy of the electron.
