The measurement of the electron position is associated with an uncertainty in momentum, which is equal to $\displaystyle 1 \times 10^{-18} \mathrm{~g} \mathrm{~cm} \mathrm{~s}^{-1}$. The uncertainty in electron velocity is,
(mass of an electron is $\displaystyle 9 \times 10^{-28} \mathrm{~g}$)
Official answer
(2)
$\displaystyle 1 \times 10^9 \mathrm{~cm} \mathrm{~s}^{-1}$
