Vedclass · Answer

(D) Heisenberg's uncertainty principle states that it is impossible to determine simultaneously the exact position and exact momentum of a microscopic particle.This principle is significant only for microscopic particles like electrons,protons,etc.It is not applicable to macroscopic objects like a $ 	ext{motor car} $ because their mass is large,making the uncertainty in position and velocity negligible.It is also not valid for $ 	ext{stationary particles} $ because their velocity is zero,and their position can be determined precisely.Therefore,the principle is not valid for both $ (b) $ and $ (c) $.

Heisenberg's uncertainty principle is not valid for:
