A golf ball has a mass of 40 g , and a speed of 45m/s. if the speed can be measured with in accuracy of 2 % . Calculate the uncertainty in the position .

Text Solution

Verified by Experts

Mass of the ball `40 g - 40 xx10^(-3) kg`
The uncertainty in the speed
`Deltav = 45 xx (2)/(100)=0.9ms^(-1)`
`Deltax = (h)/(4pimDeltav)=(6.626xx10^(-34)Js)/(4xx3.14xx(40xx10^(-3)kg)(0.9ms^(-1)))=1.46xx10^(-33)m`.
