According to Heisenberg’s uncertainty principle:
∆x. ∆p ≥ h/4π
Mass of the ball = 4 g
Speed is = 90 m /s
Uncertainity of speed, ∆v = 4/100 × 90
∆v = 3.6 m/s
∆x = h/4πm∆v
∆x = 6.26 × 10-34 / 4 × 3.14 × 4× 3.6
Hence, ∆x = 1.46 x 10-33 m
Table-tennis ball has a mass 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?
