07 Apr AB and CD are two ideal springs having force constant K1 and K2 respectively. Lower ends of these springs are attached to the ground so that the springs remain vertical. A light rod of length 3a is attached with upper ends B and C of springs. A particle of mass m is fixed with the rod at a distance a from end B.and in equilibrium, the rod is horizontal. Calculate period of small vertical oscillations of the system.
