Two particles of masses m and 4m are moving in horizontal circles. The heavier mass moves in a circle of radius , while the lighter mass moves in a circle of radius R. If both particles experience the exact same centripetal force, the speed of the lighter particle is k times the speed of the heavier particle. Find the value of k.
