Problem of the week
The centrifugal force acting on a bead that rotates around a wire ring will try to pull the ring apart. In other words, the bead rotation causes tension in the wire. The following problem explores this effect from the viewpoint of quantum mechanics.

Problem of the week - Solution
We start by calculating the energy spectrum of the system.
The tension in the ring can be found using the work-energy relation.
We now analyze the system from the viewpoint of classical mechanics.
