The correctness of velocity of an electron moving with velocity `50 ms^(-1)` is `0.005%` . The accuracy with which its position can be measured will be

Text Solution

Verified by Experts

The correct Answer is:
4

`"Here", Deltav=(0.005xx50)/(100)=0.0025ms^(-1)`
`Deltax=(h)/(mDeltav)=(1.034xx10^(-34))/(9.1xx10^(-31)xx0.0025)`
`=4634xx10^(-5)m`
