Question

The speed of an electron moving at 60m/s is measured to an accuracy of
0.05%. What would be the minimum error in determining its position?​

Answer 1

Answer:

Error in position is 1.42 x 10^-³ m

Explanation:

Δx × mΔv ≥ h/4π

mass of electron= 9.1 x 10^-³¹ kg

h/4π = 5.204 x 10^-³⁴

∆v = 60x0.05/100 = 0.03 m/s

∆x ≥ (5.204 x 10^-³⁴)/(9.1 x 10^-³¹ x 0.03)

∆x ≥ 1.42 x 10^-³ m
