If the uncertainty in position and momentum of a particle of mass 'm' are equal, then ascertain the minimum uncertainty in its velocity.

Explanation

`Deltax*Deltap gt (h)/(4pi)`
or, `Deltap*Deltap gt (h)/(4pi)" "[because Deltax=Deltap]`
or `Deltap ge(1)/(2) sqrt((h)/(pi))`
or `mxxDelta v ge(1)/(2)sqrt((h)/(pi))`
or `Deltav ge (1)/(2m) sqrt((h)/(pi))`
So the minimum uncertainty in its velocity`=(1)/(2m)sqrt((h)/(pi))`
