Beads on a hoop
Â
Two beads of mass m are initially at rest at the top of a frictionless hoop of mass M and radius R, which stands vertically on the ground. The beads are given tiny kicks, and they slide down the hoop, one to the right and one to the left, as shown in Fig. 4.23. What is the largest value of m/M for which the hoop will never rise up off the ground?
