According to the Uncertainty Principle, which of the following pairs of physical properties cannot be simultaneously measured with perfect accuracy?

  1. Position and Momentum

  2. Energy and Time

  3. Spin and Polarization

  4. Charge and Mass


Correct Option: A
Explanation:

The Uncertainty Principle states that the more precisely the position of a particle is known, the less precisely its momentum can be known, and vice versa.

The mathematical expression for the Uncertainty Principle is:

  1. $\Delta x \Delta p \ge \frac{h}{4\pi}$

  2. $\Delta E \Delta t \ge \frac{h}{4\pi}$

  3. $\Delta S \Delta P \ge \frac{h}{4\pi}$

  4. $\Delta Q \Delta M \ge \frac{h}{4\pi}$


Correct Option: A
Explanation:

The Uncertainty Principle is mathematically expressed as $\Delta x \Delta p \ge \frac{h}{4\pi}$, where $\Delta x$ is the uncertainty in position, $\Delta p$ is the uncertainty in momentum, and $h$ is Planck's constant.
