A golf ball has a mass 40g and a speed of `45 ms^(-1)`. If the speed can be measured with inaccuracy of 2%, calculate the uncertainty in position.

Text Solution

Verified by Experts

The uncertainty in speed
`= 45 xx(2)/(100) = 0.9 ms^(-1)`
`"Using the equation, "Deltax=(h)/(4piDeltavxxm)`
`Deltax=(6.626xx10^(-34)kgm^(2)s^(-1))/(4xx3.1416xx0.9ms^(-1)xx416xx0.9ms^(-1)xx40xx10^(-3)kg)`
`Deltax=1.46xx10^(-33)m`
This is nearly 1018 times smaller than the diameter of a typical atomic nucleus.
