Question
An electron in a hydrogen atom (in its ground, or lowest, energy state) has an uncertainty in its position of about 1 ✕ 10−10 m. (This is sometimes considered the "diameter" of the hydrogen atom.) The approximate speed of the electron in a hydrogen atom is about the same order of magnitude as the uncertainty in its speed. Use the uncertainty principle to estimate the speed (in m/s) of the electron in a hydrogen atom. Note that, because this is an estimate, any result within a factor of 10 of the "accepted" value will be graded as correct.
