Chapter 3.6, Problem 3.7WE
An electron in a hydrogen atom is known to have a velocity of 5 × 106 m/s ± 1 percent. Using the uncertainty principle, calculate the minimum uncertainty in the position of the electron and, given that the diameter of the hydrogen atom is less than 1 angstrom (Å), comment on the magnitude of this uncertainty compared to the size of the atom.
