The measurement of the electron position is associated with an uncertainty in momentum, which is equal to 1×10−18 g cm s−11 \times 10^{-18} \mathrm{~g} \mathrm{~cm} \mathrm{~s}^{-1}1×10−18 g cm s−1. The uncertainty in electron velocity is, (mass of an electron is 9×10−28 g9 \times 10^{-28} \mathrm{~g}9×10−28 g )
