Question

Heisenberg's Uncertainty principle is not applicable to _____.

Answer 1

Hint : We know that The Heisenberg uncertainty principle is a very important principle of the quantum world. It states that the certainty in position and momentum of a microscopic particle cannot be measured simultaneously.

Complete Step By Step Answer:
We know that Heisenberg principle states that the position and momentum of a moving microscopic particle cannot be calculated simultaneously without significant we know the position of the particle with certainty then the momentum of the particle will have maximum uncertainty. In the same way if we know the momentum of the particle with certainty then the uncertainty in the position of the particle will be maximum. The product of uncertainty in position and momentum is greater than or equal to $\frac{h}{4\pi }.$
From the statement of the principle it is clear that it is applicable to moving microscopic particles only. So, we can measure the certainty in both position and momentum of a motor car. The Heisenberg's principle is valid only for micro particles as the large bodies are easy to analyze. Thus, Heisenberg's Uncertainty principle is not applicable to all the bodies moving with high speed

Note :
Remember that the uncertainty principle is because of the wave nature of the particles. In large objects the wave nature is not much visible because of the very large mass of the object. So the uncertainty is much less in calculating position and momentum.
