What is the uncertainty in the position ...

What is the uncertainty in the position of electron, if uncertainty in its velocity is 0.006 m/s ?

Text Solution

Verified by Experts

`Delta x xx Deltav=(h)/(4 pi m)`, therefore, uncertainty in the position, `Delta x=(h)/(4pi m Deltav)`
`Delta x =(6.626xx10^(-34)"kgm"^(2)s^(-1))/(4.314xx9.1xx10^(-31)kg xx 0.006ms^(-1))=0.966 xx 10^(-2)m`

Werner Heisenberg considered the limits of how precisely we can measure the properties of an electron or other microscopic particle. He determined that there is a fundamental limit to how closely we can measure both position and momentum. The more accurately we measure the momentum of a particle, the less accurately we can determine its position. The converse is also true. This is summed up in what we now call the Heisenberg uncertainty principle. The equation is Delta x Delta (mv) ge (h)/(4 pi) The uncertainty in the position or in the momentum of a macroscopic object like a baseball is too small to observe. However, the mass of microscopic object such as an electron is small enough for the uncertainty to be relatively large and significant. If the uncertainties in position and momentum are equal, the uncertainty in the velocity is:

If the uncertainty in velocity and position is same, then the uncertainty in momentum will be:

The uncertainty in position of an electron is equal to its de-Broglie wavelength. The minimum percentage error in its measurement of velocity under this circumstances will be approximately
