The uncertainity in the position and vel...

The uncertainity 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? (Value of Planck's constant is `6.6xx10^(-34)Js`) 

Text Solution

Verified by Experts

`Deltax=10^(-10)m,Deltav=5.25xx10^(-24)ms^(-1)`
Mass of the moving particle (m) `=(6.6xx10^(-34)kgm^(2)s^(-1))/(4xx3.1416xx10^(-10)mxx5.25xx10^(-24)ms^(-1))=0.1001kg`
