Question

calculate the uncertainty in the position of an electron if uncertainty in its velocity is equal to 0.001 % and 0 mass of the electron 9.1 into 10 ^ - 31 kg weight loss calculate velocity is e 300 metre per second​

Answer 1

Answer:

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.
