One is equivalent to 931 MeV energy. The rest mass of electron is 9.1 $	imes 10^{- 31}$kg. the Mass equivalent energy is (1 amu $= 1.67 	imes 10^{- 17}$kg)

Dr. Abubacker · Accepted Answer

The mass of electron $= \frac{9.1 	imes 10^{- 31}}{1.67 	imes 10^{- 27}}$ $	herefore E = \frac{9.1 	imes 10^{- 31}}{1.67 	imes 10^{- 27}} 	imes 931\$MeV $= 0.5073$ MeV

Q. One is equivalent to 931 MeV energy. The rest mass of electron is 9.1 $\times 10^{- 31}$kg. the Mass equivalent energy is (1 amu $= 1.67 \times 10^{- 17}$kg)
