Question
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.
Solution
The uncertainty principle is significantly only for the microscopic particles and not for the macroscopic particles can be concluded by considering the following example.
Let us consider a particle or an object of mass 1 milligram i.e. 10–6 kg
Then its uncertainty can be calculated as,
`∆x. ∆ν = (6.626 xx 10^-34)/(4 xx 3.14 xx 10^-16)`
= 10–28 m–2 s–1
Thus the value obtained is negligible and insignificant for the uncertainty principle to be applied to this particle.
