An electron has a speed of `40m//s`, accurate up `99.99%`.What is the uncertainty in locating position ?

Text Solution

Verified by Experts

The correct Answer is:
`0.0144m`
`v=40m//sec" "Deltav=0.01`
`therefore Deltax = (h)/(4pixx9.1xx10^(-37)xx99.99xx40)`
`=(0.53xx100xx10^(-54))/(40xx99.99xx9.1xx10^(-37))`
`=(0.53xx10^(-3)xx100)/(40xx9.1xx99.99)" "m.Deltax.Deltax=(h)/(4pi)`
`Deltax=(5.27xx10^(-34))/(9.1xx10^(-31)xx40xx0.04xx(1)/(100))=1.447xx10^(-3)xx100`
