If the positionof theelectronis measuredwithinan accuracyof +0.002nmcalculatetheuncertaintyin themomentumoftheelectronSupposethe momentumof the electronish// 4pi_(m) xx 0.05 nmis there any problemin definingthisvalue ?

Answer»

<P>

Solution :Uncertaintyin VELOCITY`(DELTA p ) `
Accordingto Heisenberg
`DELTAP = (h)/(4pi Delta x)`
`=(6.626 xx 10^(34) js )/( (4xx 3.1428)(0.002 xx 10^(9) m))`
`Delta p= 2.63854xx 10^(23) kgms^(-1)`
Realmomentumof electron= `(h)/(4pi xx 0.05 nm)`
In THISWAY realmomentum `1.054 xx 10^(24) ` is less thancalculatedvalue ofuncertainty`2.64 xx 10^(23)` So the momentumof electroncan notbedefineproperly.
