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

Explanation

`Delta x Deltap= ("or") Delta xm Delta v = (h)/(4pi)`
`Delta v = (h)/(4 pi Delta x m)`
`Delta v = (6.626 xx 10^(-34) Js)/(4 xx 3.14 xx0.1 xx 10^(-10) m xx 9.11 xx 10^(-31) kg)`
`= 0.579 xx 10^(7) ms^(-1) (1 J = 1kgm^(2) s) `
`=5.70 xx 10^(6) ms^(-1)`
