Question

A golf ball has a mass of 40g, and a speed
of 45 m/s. If the speed can be measured
within accuracy of 2%, calculate the
uncertainty in the position.
​

Answer 1

Explanation:

Here, Δx is the uncertainty in the position.

Δv is the uncertainty in velocity

m is the mass of Particle.

Given,m=40g=0.04kg

Δv=2%ofv=2×

100

45

=0.9m/s

h=6.626×10

−34

J.s

Now,Δx=

(4×3.14×0.04×0.9)

6.626×10

−34

=1.4654×10

−33

m
