Question:
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.
Solution:
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.
