The effect of the uncertainty principle is significant only for the motion of microscopic particles and is negligible for macroscopic particles. Justify the statement with the help of a suitable example.

(N/A) The Heisenberg uncertainty principle is given by $\Delta x \cdot \Delta v \geq \frac{h}{4 \pi m}$.
For a microscopic particle like an electron $(m = 9.11 \times 10^{-31} \ kg)$,the uncertainty is significant.
For a macroscopic object of mass $1 \ mg$ $(10^{-6} \ kg)$:
$\Delta x \cdot \Delta v = \frac{h}{4 \pi m} = \frac{6.626 \times 10^{-34} \ J \ s}{4 \times 3.1416 \times 10^{-6} \ kg} \approx 0.527 \times 10^{-28} \ m^2 \ s^{-1}$.
This value is extremely small and physically insignificant,which is why the uncertainty principle is negligible for macroscopic objects.

What does the uncertainty principle state regarding the existence of a definite path or trajectory of an electron?

The uncertainty in the position of an electron moving with a velocity of $3 \times 10^4 \ cm/s$ is (given mass of electron $= 9.1 \times 10^{-28} \ g$,uncertainty in velocity $= 0.02 \ \%$).

If the uncertainty in velocity of electron $(\Delta v)$ is $0.1 \ m/s$,the uncertainty in its position $(\Delta x)$ is (given: $m_e = 9.1 \times 10^{-31} \ kg$)
