A circular spring of natural length l0 is cut and welded with two beads of masses m1 and m2 such that the ratio of the lengths of the springs between the beads 4:1. If the stiffness of the original spring is k,

A sphere of mass m and radius r rolls without slipping on a rough concave surface of large radius R. It makes small oscillations about the lowest point. Find the time period.
