The uncertainty in the position of electron $(\Delta x)$ is approximately 100 pm. The uncertainty in momentum (in $\mathrm{kg} \mathrm{m} \mathrm{s}^{-1}$ ) of an electron is $\left[\mathrm{h}=6.626 \times 10^{-34} \mathrm{Js}\right]$

• A

  $1.104 \times 10^{-22}$
• B

  $0.527 \times 10^{-27}$
• Correct answer
  C

  $0.527 \times 10^{-24}$
• D

  $1.055 \times 10^{-24}$

Hence, the correct answer is option: 'C'.
