A tray of mass $12 \,kg$ is supported by two identical springs as shown in figure. When the tray is pressed down slightly and then released, it executes SHM with a time period of $1.5\,s$. The spring constant of each spring is
A piston is performing S.H.M. in the vertical direction with a frequency of 0.5 Hz. A block of 10 kg is placed on the piston. The maximum amplitude of the system such that the block remains in contact with the piston is
Two simple pendulums $A$ and $B$ are made to oscillate simultaneously and it is found that $A$ completes $10$ oscillations in $20\, sec$ and $B$ completes $8$ oscillations in $10\, sec$. The ratio of the lengths of $A$ and $B$ is

The ratio of kinetic energy to the potential energy of a particle executing $SHM$ at a distance equal to half its amplitude, the distance being measured from its equilibrium position is
A $10\,kg$ metal block is attached to a spring of spring constant $1000 \, nm^{-1}$. A block is displaced from equilibrium position by $10\,cm$ and released. The maximum acceleration of the block is
From a fixed support,two small identical spheres are suspended by means of strings of length $1\, m$ each .They are pulled aside as shown and then released $B$ is the mean position.Then the two spheres collide.
The circular motion of a particle with constant speed is
A particle executing a simple harmonic motion has a period of $6\,sec$. The time taken by the particle to move from the mean position to half the amplitude, starting from the mean position is.
A simple pendulum is suspended from the ceiling of a lift. When the lift is at rest its time period is $T$. With what acceleration should the lift be accelerated upwards in order to reduce its period to $T/2$ ? (g is acceleration due to gravity).
A particle on trough of a wave at any instant will come to mean position after time (T=time period)
