If uncertainty in position and velocity are equal the uncertainty in momentum will be

Text Solution

Verified by Experts

`Delta x.m. Delta v = (h)/(4pi)`,here `Deltax = Delta v` (given),
Therefore, `Delta x = sqrt((h)/(m 4pi))`….(i) But also `Delta p = (h)/(4pi.Deltax)`…(ii)
From equation (i) and (ii), we get `Deltap = (1)/(2) sqrt((mh)/(pi))`

If uncertainty in position are velocity are equal the uncertainty in momentum will be

If uncertainty in position and momentum are equal then uncertainty in velocity is.

It is not possible to determine preciselt both the position and momentum (or velocity) of a small moving particle such as electron, proton etc. This is known as Heisenber uncertainty principle. The mathemactical form of this principle is : Delta x.Delta p ge (h)/(4pi) (constant) However this principle is irrevalent in case of bigger particles such as a cup, ball, car etc., that we come across in our daily life. If uncertainty in position and momentum are equal, the v uncertainty in velocity would be

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 also true. This is summed up in what we now call the Heisenberg uncertainty principle. The equation si deltax.delta (mv)ge(h)/(4pi) The uncertainty in the position or in the momentum of a marcroscopic object like a baseball is too small to observe. However, the mass of microscopic object such as an electon is small enough for the uncertainty to be relatively large and significant. If the uncertainty in velocity and position is same, then the uncertainty in momentum will be :
