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

Text Solution

Verified by Experts

Given, `Delta v = (0.01)/(100) xx 40 = 0.004 ms^(-1)`
we know, `Deltax.Delta v ge (h)/(4pim)`
`Delta x ge (h)/(4pi mDelta v)`
`Delta x = (6.625 xx 10^(-34))/(4 xx 3.14 xx 9.1 xx 10^(-31) xx 0.004)`
`Delta x = 1.45 xx 10^(-2)m`
