Uncertainty in position of a minute particle of mass 25 g in space is $10^{-5}\mathrm{~m}$. What is the uncertainty in its velocity (in $\mathrm{ms}^{-1}$)? ($\mathrm{h} = 6.6 \times 10^{-34}\,\mathrm{Js}$)\\
(1) $2.1 \times 10^{-34}$\\
(2) $0.5 \times 10^{-34}$\\
(3) $2.1 \times 10^{-28}$\\
(4) $0.5 \times 10^{-23}$
