Sample Problem 7.4
SOLUTION:
PLAN:
Applying the Uncertainty Principle
The uncertainty in the speed (Du) is given as 1% (0.01) of 6 x 106 m/s. Once we calculate this value, the uncertainty equation is used to calculate Dx.
Du = (0.01)(6 x 106 m/s) = 6 x 104 m/s (the uncertainty in speed)
Dx
4p (9.11 x 10-31 kg)(6 x 104 m/s)
6.626 x 10-34 kg.m2/s
1 x 10-9 m
