Question

Calculate the uncertainty in the velocity of an electron is the uncertainty in its position is 12pm

Answer 1

Answer:

How do you find the uncertainty of an electron velocity?

The uncertainty in position is the accuracy of the measurement, or Δx = 0.0100 nm. Thus the smallest uncertainty in momentum Δp can be calculated using ΔxΔp≥h4π Δ x Δ p ≥ h 4 π . Once the uncertainty in momentum Δp is found, the uncertainty in velocity can be found from Δp = mΔv
