To solve the problem using Heisenberg's uncertainty principle, we will follow these steps: ### Step 1: Understand Heisenberg's Uncertainty Principle Heisenberg's uncertainty principle states that the product of the uncertainties in position (Δx) and momentum (Δp) is greater than or equal to a constant, given by: \[ \Delta x \cdot \Delta p \geq \frac{h}{4\pi} \] where \( h \) is Planck's constant. ...
