The effect of the uncertainty principle


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


The uncertainty principle is only significantly applicable for microscopic particles and not macroscopic particles this can be concluded from the measurement of uncertainty:

For example, if we take a particle or an object of mass 1 milligram i.e. 10-6 kg )

We calculate the,

∆x. ∆ν = 60626*10-34/ 4*3.14*10-6

= 10-28 m-2 s -1

The value we got is negligible and very insignificant for the uncertainty principle to apply to the particle.
