A cricket ball weighing 100 g is located within 1 nm. What is the uncertainty in the velocity ?

Answer» Correct Answer - `5.27xx10^(-25)m s^(-1)`
According to uncertainty principle
`Delta x *m Deltav=(h)/(4 pi) or Deltav=(h)/(4pixxmxxDeltax)`
`h=6.626xx10^(-34)"kg"m^(2)s^(-1), m=100g=0.1 "kg", Deltax=1nm=10^(-9)m, pi=3.143`
`Deltav=[((6.626xx10^(-34)"kg" m^(2)s^(-1)))/(4xx3.143xxx(0.1"kg")(10^(-9)m))]" " =5.27xx10^(-25)m s^(-1)`.
