Updated On: May 1, 2026
- Proton
- Methane
- Both (A) and (B)
- $1\,\mu$m sized platinum particles
- $1\,\mu$m sized NaCl particles
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Heisenberg Uncertainty Principle: \[ \Delta x \cdot \Delta p \geq \frac{h}{4\pi} \] It applies to all microscopic particles.
Step 1: Microscopic systems.
Proton and molecules like methane follow quantum mechanics.
Step 2: Macroscopic systems.
Large objects have negligible uncertainty.
