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 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 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 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
