If we consider mass as 10-6 kg (1 milligram), then we know that

\Delta v.\Delta x=h/4\pi m

=\Delta v.\Delta x=h/4\times 3.14\times 10^{-6}

=6.626\times 10^{-34}/4\times 3.14\times 10^{-6}

=0.52\times 10^{-28}m^{2}s^{-1}

As the value is negligible and is highly insignificant for the uncertainty principle to be applicable to the particle.
