Calculate the uncertainty in velocity (\( \Delta v \)) of an electron if the uncertainty in its position (\( \Delta x \)) is \( 10^{-8} \text{ m} \). (Given: mass of electron \( m = 9.11 \times 10^{-31} \text{ kg} \), Planck's constant \( h = 6.626 \times 10^{-34} \text{ J s} \))

1. A
   \( 5.79 \times 10^6 \text{ m s}^{-1} \)
2. B
   \( 7.21 \times 10^3 \text{ m s}^{-1} \)
3. C
   \( 3.16 \times 10^4 \text{ m s}^{-1} \)
4. D
   \( 1.04 \times 10^5 \text{ m s}^{-1} \)
