The uncertainty in position and velocity...

The uncertainty in position and velocity of a particle are `1.0xx10^(-5)`m and `4.28xx10^(-20)m*s^(-1)` respectively. Calculate the mass of the particle.

Text Solution

Verified by Experts

`m=(h)/(4piDeltax Deltav)=(6.626xx10^(-34))/(4xx3.14xx(1.0xx10^(-5))xx(4.28xx10^(-20)))`
`=1.23xx10^(-10)kg`
