Task 60068.

Using the uncertainty relation, estimate the minimum velocity of an electron in a hydrogen atom, based on the fact that the radius of the atom is of the order of 0.1 nm. (Assume that the uncertainty Δr of the radius r of the electron orbit and the uncertainty Δp of the electron momentum p in such an orbit are related by the relations: Δr ~ r and Δp ~ p.
