Question

In an atom, an electron is moving with a speed of 600m/s with an accuracy of 0.005%. What is the certainity with which the position of the electrons can be located?
(h= 6.6*10-34 kg m2/s, mass of electron = 9.1*10-31 kg)

Answer 1

explanation

ANSWER

m=9.1×10−31 kg

Δx×mΔv≥4πh

Δv=600×1000.005=0.03

Δx≥4mΔvπh

≥4×9.1×10−31×0.03×
