The uncertainty in position and velocity...

The uncertainty in position and velocity of the particle are 0.1 nm and `5.27xx10^(-24) ms^(-1)` respectively then find the approximate integral mass of the particle (in g ) . `(h=6.625xx10^(-34) Js)`

Text Solution

Verified by Experts

According to Heisenberg's uncertainty principle,
`Deltax*mDeltav=(h)/(4pi)`
or `m=(h)/(4piDeltax*Deltav)`
`=(6.625xx10^(-34))/(4xx3.143xx10^(-10)xx5.27xx10^(24))`
`=0.099kg`.
