An electron has a speed of 500m s^(-1) ...

An electron has a speed of 500m `s^(-1)` with uncertainty of 0.02% . What is the uncertainty in locating its position ?

Text Solution

Verified by Experts

The correct Answer is:
`5.77 xx 10^(-4) m`
Uncertainty in speed `(Delta v) = (0.02)/(100) xx 500 m s^(-1) = 0.1 ms^(-1)`
