Table-tennis ball has mass 10g and s peed of 90m/s. if speed can be meausred within an accuracy of 4%. What will be the uncertainly in speed and position?

Explanation

Given that, speed =90m/s ltbr. Mass=`10g=10xx10^(-3)kg`
Uncertainly in speed `(DeltaV)=4%"of"90ms^(-1)=(4xx90)/(100)=36ms^(-1)`
From Heisenberg uncertainty principle.
`Deltax.Deltav=(h)/(4pim)`
`Deltax=(h)/(4pimDeltav)` ltbr. Uncertainly in position `Deltax=(6.626xx10^(-34)kgm^(2)s^(-1))/(4xx3.14xx10xx10^(-3)kgxx3.6ms^(-1))`
`=1.46xx10^(-33)m`
