Given : The mass of electron is $9.11\times 10^{-31}\text{kg}$ plank constant is $6.626\times 10^{-34}\text{Js}$, the uncertainty involved in the measurement of velocity within a distance of $0.1\text{A˚}$ is :

1. A
   $5.79\times 10^6{\text{ms}}^{-1}$
2. B
   $5.79\times 10^7{\text{ms}}^{-1}$
3. C
   $5.79\times 10^8{\text{ms}}^{-1}$
4. D
   $5.79\times 10^5{\text{ms}}^{-1}$
