The measurement of the electron position is associated with an uncertainty in momentum, which is equal to \( 1 \times 10^{-18} \mathrm{gcms}^{-1} \)
a) The uncertainty in electron velcoity is, (mass of an electron is \( 9 \times 10^{-28} \mathrm{~g} \) )
1) \( 1 \times 10^{5} \mathrm{cms}^{-1} \)
2) \( 1 \times 10^{11} \mathrm{cms}^{-1} \)
3) \( 1 \times 10^{9} \mathrm{cms}^{-1} \)
-4) \( 1 \times 10^{6} \mathrm{cms}^{-1} \)
