Two very small balls, each having mass m, are attached to two massless rods of length l. Now these rods are joined to form V like figure having angle $$60$$°. This assembly is now hinged in a vertical plane so that it can rotate without any friction about a horizontal axis (perpendicular$$ to the plane of $$figure) as shown in the figure. The period of small oscillation of this assembly is
