The uncertainty in the position of a flying dust particle of mass \( 0.1 \mathrm{mg} \) is found to be \( 10^{-4} \mathrm{~m} \). The uncertainty in the
\( \mathrm{P} \)
position of another flying dust particle of mass \( 0.5 \mathrm{mg} \) is also found to be same.

The uncertainty in the velocity of the heavier dust particle as compared to the lighter dust particle is
(1) 5 times
(2) \( 1 / 5^{\text {th }} \) times
(3) Same
(4) 50 times
