Find the energy equivalence of the mass of an electron.

3 years ago

Mass-energy equivalence is calculated by the formula E=mc^{2}

To find this we need the mass of an electron (9.11x10^{-31 }kg) and the speed of light (c = 3.0010^{8}m/s)

E = (9.11x10^{-31 }kg)(3.00x10^{8}m/s)^{2 }

E = 8.199x10^{-14 }J
