A block of mass m is connected to three springs as shown in Fig. The block is displaced down slightly and left free, it starts oscillating. Find time period of oscillations.

A wire of length l, area of cross-section A and Young,s modulus of elasticity Y is suspended form the roof of a building. A block of mass m is attached at lower end of the wire. If the block is displaced from its mean position and released then the block starts oscillating. Time period of these oscillations will be
