The effect of uncertainty principle is significant only for motion of microscopic particles and is negligible for the macroscopic particles. Justify the statement with the help of a suitable example.

Explanation

If uncertainty principle is applied to an object of mass, say about a milligram `(10^(-6)kg)`, then
`Delta.Deltax=(h)/(4pim)`
`Deltav.Deltax=(6.626xx10^(-34)kgm^(2)s^(-1))`
`=0.52xx10^(-28)m^(2)s^(-1)`
The value of `Deltav.Deltax` obtianed is extermeely small and is insignificant. Therefore, for miligram-sized or heavier objects, the associated uncertainties are hardly of any real consequence.
