Table-tennis ball has a mass of 10 g and a speed of 90 m/s. If speed can be measured within an accuracy of 4%, what will be the uncertainty in speed and position?

Options

  1. AUncertainty in speed = 3.6 m/s, Uncertainty in position = 3.24 × 10 -34 m
  2. BUncertainty in speed = 36 m/s, Uncertainty in position = 1.46 × 10 -33 m
  3. CUncertainty in speed = 0.36 m/s, Uncertainty in position = 1.26 × 10 -34 m
  4. DUncertainty in speed = 0.36 m/s, Uncertainty in position = 3.24 × 10 -34 m

Correct answer

B. Uncertainty in speed = 36 m/s, Uncertainty in position = 1.46 × 10 -33 m

Step-by-step solution

Correct Option is : (B) Uncertainty in speed = 36 m/s, Uncertainty in position = 1.46 × 10 -33 m
