A block of mass `m` is attached to a block of mass `4m` is hanging from a spring of spring constant `K` .The blocks are in the state of rest. Blocks of mass `m` will rise if block of mass `4m` gently falls away is `(beta mg)/(k)` .The value of `beta` is

A block of mass m suspended from a spring of spring constant k . Find the amplitude of S.H.M.

A block of mass m is connected to another .block of mass M by a massless spring of spring constant k. A constant force f starts action as shown in figure, then:

A block of mass m is connect to another block of mass M by a massless spring of spring constant k. The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is upstretched when a constant force F starts acting on the block of mass M to pull it. Find the maximum extension of the spring.

A block of mass m is connect to another block of mass M by a massless spring of spring constant k. The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is unsrtretched when a constnt force F starts acting on the block of mass M to pull it. Find the maximum extension of the spring.

A block of mass m is suspended by different springs of force constant shown in figure.

A block of mass 'm' is connected to another block of mass 'M' by a spring (massless) of spring constant 'k' The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is unstretched Then a constant force 'F' starts acting on the block of mass 'M' to pull it. Find the force on the block of mass 'm' :

A block of mass m is connected to another block of mass M by a massless spring of spring constant k . the blocks are kept of a smooth horizontal plane and are at rest. The spring is unstretched when a constant force F starts acting on the block of mass M of pull it. Find the maximum extension of the spring

A block of mass m is connected to another block of mass M by a massless spring of spring constant K . Blocks are kept on a smooth horizontal plane. Initally both the blocks the at rest and spring is unstressed. Force F is applied on M to right as shownin the figure then which of the following is correct ?

A block of mass m is attached to a cart of mass 4m through spring of spring constant k as shown in the figure. Friction is absent everywhere. The time period of oscillations of the system, when spring is compressed and then released, is

A block of mass m hangs from a vertical spring of spring constant k. If it is displaced from its equilibrium position, find the time period of oscillations.
