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

Explanation

Uncertainity in the position, `Deltax=0.1Å=10^(-11)m`
`Deltax.m.Deltav=(h)/(4pi),Deltav=(h)/(4pimDeltax)=(6.625xx10^(-34))/(4xx3.14xx9.11xx10^(-31)xx10^(-11))`
Uncertainity involved in the measurement of velocity is `5.79 xx 10^(6) ms^(-1)`
