The uncertainty in the position and velo...

The uncertainty in the position and velocity of a particle are `10^(-10)m` and `5.25 xx 10^(-24) ms^(-1)`. What is the mass of the particle ? `(h = 6.625 xx 10^(-34) Js)`

Text Solution

Verified by Experts

`Deltax=10^(-10)m"        "Deltav=5.25xx10^(24)ms^(-1)`
`m=(6.625xx10^(-34)kgm^(2)s^(-1))/(4xx3.1416xx10^(-10)mxx5.25xx10^(-24)ms^(-1))`
`"Mass of a particle" =" 0.1004 kg or 100.4 g "`
