If uncertainty in position and momentum are qual, that minimum uncertainty in velocity is

Answer»

`1/m SQRT(H/pi)`
`sqrt(h/pi)`
`1/(2m) sqrt(h/pi)`
`h/(4pi)`

Solution :`Deltax . DELTAP GE h/(4pi)`
`Deltap.Deltap ge h/pi`
`Deltap^2 ge h/(4pi)`
`m^2(Delta V)^2 ge h/(4pi)`
`(Delta V) ge sqrt((h)/(4pi m^2))`
`Delta V ge 1/(2m) sqrt(h/pi)`
