The mass of an electron is 9.11 x 10-31 kg and the diameter of a hydrogen atom is 100 pm (100 x 10-12 m). As the electron could be located anyway throughout the volume of the hydrogen atom, the maximum uncertainty in the position of the electron, Ax, can be estimated to be < 100 pm. Determine the minimum uncertainty in the speed of an electron in a hydrogen atom.
