Two blocks A and B, each of mass m are connected by means of a pulley-spring system on a smooth inclined plane of inclination q as shown in the figure. All the pulleys and spring are ideal. Now, B is slightly displaced from its equilibrium position. It starts to oscillate. Time period of oscillation of B will be  (Take m = 4 kg, K = 5 N/m, p = 3.14)
