Suppose a macroscopic bead with a mass of 2.0 g is constrained to move on a straight
Question:
Suppose a macroscopic bead with a mass of 2.0 g is constrained to move on a straight frictionless wire between two heavy stops clamped firmly to the wire 10 cm apart. If the bead is moving at a speed of 20 nm/y (i.e., to all appearances it is at rest), what is the value of its quantum number n?
