Calculate the uncertainty in the velocity of a cricket ball of mass `150g`, if the uncertainty in its position in of the orer of `1Å`.
`(h=6.6xx10^(-34)kg " "m^(2) s^(-1))`

Text Solution

Verified by Experts

`Deltax*mDeltav=(h)/(4pi)`
`Deltav=(h)/(4piDeltax*m)`
`=(6.6xx10^(-34))/(4xx3.143xx10^(-10)xx0.150)`
`=3.499xx10^(-24)ms^(-1)`.
