A tray of mass 12 kg is supported by two identical springs as shown in figure. When the tray is pressed down slightly and released, it executes SHM with a time period of 1.5s. What is the force constant of each spring?When a block of mass m is placed on the tray , the period of SHM changes to 3.0s. What is the mass of the block ?

A tray of mass M=10kg is supported on two identical springs, each of spring constant k, as shown in figure, when the tray is depressed a little and released, it executes simple harmonic motion of period 1.5 s. when a blockof mass m is placed on the tray, the speed of oscillation becomes 3 s. the value of m is

A plank of mass 12 kg is supported by two identical springs as shown is Fig. The plank always remains horizontal. When the plank is pressed down and released it performs simple harmonic motion with time period 3 s. When a block of m is attached to the plank the time priod changes to 6 s. The mass of the block is

A solid sphere of density sigma with one -third of tis volume submerged . When the sphere is pressed down slightly and released , it executes S.H.M of time period T. Then (viscous effect is ignored)

An arrangement of three identical spring and a block of mass 10 kg is shown in the adjoining figure. When the platform on which block is placed is slightly pressed down and released. It performs S.H.M. with a period of 2 s. (i) Calculate the spring constant of the spring. (ii) If a block of mass m is further placed on the platform, the new period of S.H.M. becomes 3.5 s. Find the value of m. (Assume platform to be massless)

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 body of mass m is suspended from three springs as shown in figure. If mass m is displaced slightly then time period of oscillation is

A mass m is attached with rods as shown in figure. This mass is slightly stretched and released whether the motion of mass is S.H.M. if yes then find out the time period.

A spring mass system has time period of 2 second. What should be the spring constant of spring if the mass of the block is 10 grams ?
