The measurement of the electron position is associated with an uncertainty in momentum, which is equal to 1 \times 10^{-18} {\g} {\cm} {\s}^{-1}. The uncertainty in electron velocity is : (Mass of an electron is 9 \times 10^{-28} {\g} )

Correct Answer is : 1×109cms−1

1 \times 10^{11} {\cm} {\s}^{-1}
