The correct Answer is:
To solve the problem of calculating the uncertainty in position (Δx) given the uncertainty in momentum (Δp) and Planck's constant (h), we can use Heisenberg's uncertainty principle. Here’s the step-by-step solution: ### Step 1: Understand the Heisenberg Uncertainty Principle The Heisenberg uncertainty principle states that the product of the uncertainties in position (Δx) and momentum (Δp) is always greater than or equal to a constant value: \[ \Delta x \cdot \Delta p \geq \frac{h}{4\pi} \] ### Step 2: Rearrange the Formula We want to find the uncertainty in position (Δx). Therefore, we can rearrange the formula to solve for Δx: \[ \Delta x \geq \frac{h}{4\pi \Delta p} \] ### Step 3: Substitute the Given Values We have: - Planck's constant, \( h = 6.6 \times 10^{-34} \, \text{J-sec} \) - Uncertainty in momentum, \( \Delta p = 3.3 \times 10^{-2} \, \text{kg m/s} \) Now we can substitute these values into the rearranged formula: \[ \Delta x \geq \frac{6.6 \times 10^{-34}}{4\pi (3.3 \times 10^{-2})} \] ### Step 4: Calculate the Denominator First, calculate \( 4\pi \): \[ 4\pi \approx 12.566 \] Now, calculate the product: \[ 4\pi \Delta p = 12.566 \times 3.3 \times 10^{-2} \] \[ 4\pi \Delta p \approx 0.415 \] ### Step 5: Calculate Δx Now substitute this back into the equation for Δx: \[ \Delta x \geq \frac{6.6 \times 10^{-34}}{0.415} \] Perform the division: \[ \Delta x \geq 1.587 \times 10^{-33} \, \text{m} \] ### Step 6: Final Result Thus, the uncertainty in position (Δx) is: \[ \Delta x \geq 1.59 \times 10^{-33} \, \text{m} \] ### Summary The uncertainty in the position of the particle is approximately \( 1.59 \times 10^{-33} \, \text{m} \). ---
