For a particle moving in a circular orbit, the quantity mvr (mass x velocity x radius of the orbit) is a fundamental quantity called the angular momentum of the particle. Show that equation 2(3.144)r=n(lambda) is equivalent to the condition that the angular momentum of the electron in a hydrogen atom must be an integral multiple of h/2(3.144).
