The center of a disk of radius r and mass m is attached to a spring of spring constant k, inside a ring of radius R > r. The disk rolls without slipping along the inside periphery of the ring. The spring follows the periphery of the ring and obeys Hooke's law. In equilibrium, the disk is at the bottom of the ring. For a small displacement, T = 2π/ω. The correct expression for ω is:
