A microscope using suitable photons is employed to locate an electron in an atom within a distance of 0.1 Å . What is the uncertainty involved in the measurement of its velocity ?

Text Solution

Verified by Experts

`DeltaxxDeltap=(h)/(4pi) or DeltaxxmDeltav=(h)/(4pi)`
`Deltav=(h)/(4piDeltaxxm)`
`Deltav=(6.626xx10^(-34)Js)/(4xx3.14xx0.1xx10^(-10)mxx9.11xx10^(-31)kg)`
`=0.579xx10^(7)ms^(-1)(1J=1kgm^(2)s^(-2))`
`=5.79xx10^(6)ms^(-1)`
