Question

State Heisenberg's uncertainly principle. Write the mathematical expression also. Why is it not applicable to macro or large particles? Explain.

Answer 1

Heisnberg uncertainity principle states that the position or momentum of any oject cannot be exactly determined. Expression he gave is

${\Delta }_x\times {\Delta }_p⩾\frac{h}{4\pi }$

it is applicable for large perticles too but we cann't observe in that case as the value of $h$ is too small and that of mass is too high.
