Accuracy in momentum of electron moving with velocity of 50 ms^(-1) is 0.005 %. Then accuracy in its position is…..

Answer»

`2.32xx10^(-2)m`
`46xx10^(-4)m`
`46xx10^(-3)m`
`46xx10^(-6)m`

SOLUTION :Momentum of electron p=mv
`therefore` uncertainty in momentum
`=mvxx0.005%`
`=9.1xx10^(-31)xx50xx(0.005)/(100)`
`=2.275xx10^(-33)kg ms^(-1)`
Corresponding uncertainty In position ,
`Deltax=(H)/(2piDeltaP)`
`=(6.625xx10^(-34))/(2xx3.14xx2.275xx10^(-33))`
