The correct Answer is:
To solve the problem, we will use the Heisenberg Uncertainty Principle, which states that the product of the uncertainties in position (Δx) and momentum (Δp) of a particle is given by the equation: \[ \Delta x \cdot \Delta p \geq \frac{h}{4\pi} \] Where: - \( \Delta x \) = uncertainty in position - \( \Delta p \) = uncertainty in momentum - \( h \) = Planck's constant (given as \( 6.62 \times 10^{-34} \, \text{kg m}^2/\text{s} \)) ### Step-by-Step Solution: 1. **Identify the given values**: - Uncertainty in momentum, \( \Delta p = 1 \times 10^{-5} \, \text{kg m/s} \) - Planck's constant, \( h = 6.62 \times 10^{-34} \, \text{kg m}^2/\text{s} \) 2. **Use the Heisenberg Uncertainty Principle**: - Rearranging the equation to solve for \( \Delta x \): \[ \Delta x = \frac{h}{4\pi \Delta p} \] 3. **Substitute the values into the equation**: - First, calculate \( 4\pi \): \[ 4\pi \approx 4 \times 3.14 \approx 12.56 \] - Now substitute \( h \) and \( \Delta p \): \[ \Delta x = \frac{6.62 \times 10^{-34}}{12.56 \times 1 \times 10^{-5}} \] 4. **Calculate the denominator**: \[ 12.56 \times 1 \times 10^{-5} = 1.256 \times 10^{-4} \] 5. **Calculate \( \Delta x \)**: \[ \Delta x = \frac{6.62 \times 10^{-34}}{1.256 \times 10^{-4}} \approx 5.27 \times 10^{-30} \, \text{m} \] ### Final Answer: The uncertainty in the position of the electron is approximately: \[ \Delta x \approx 5.27 \times 10^{-30} \, \text{m} \]
