Question
Explain why the uncertainty principle is significant only for the motion of sub-atomic particles but is negligible for the macroscopic objects?
✓

Answer

The energy of photon is sufficient to disturb a sub-atomic particle so that there is uncertainty in the measurement of position and momentum of the sub-atomic particle. However, the energy is insufficient to disturb a macroscopic object.
