The correctness of velocity of an electron moving with velocity 50 m/s is 0.005 %. the accuracy with which it position can be measured will be

Q: The correctness of velocity of an electron moving with velocity 50 m/s is 0.005 %. the accuracy with
which it position can be measured will be

Sol: $\large \Delta v = 50 \times \frac{0.005}{100}$

= 0.0025 m/s

$\large \Delta x = \frac{h}{m \Delta v}$

$\large \Delta x = \frac{6.62 \times 10^{-34}}{9.1 \times 10^{-31} \times 0.0025}$

= 4634  × 10-5 m
