Molten-wax of mass m drops on a block of mass, M which is oscillating on a frictionless table. Select the incorrect option.

Two springs are connected to a block of mass M is placed on a frictionless surface as shown in figure. If both springs have a spring constant k, the frequency of oscillation of the block is………

A block of mass m rests on a wedge of mass M which, in trun, rests on a horizontal table, as shown in figure. All surfaces are frictionless. If the system starts at rest with point P of the block a distance h above the table, find the speed of the wedge the instant point P touches the table.

A block of mass M placed on a frictionless horizontal table is pulled by another block of mass m hanging vertically by a massless string passing over a frictionless pulley. The tension in the string is :

A block of mass M placed on a frictionless horizontal table is pulled by another block of mass m hanging vertically by a massless string passing over a frictionless pulley. The tension in the string is :

Two blocks of masses m and m' are connected by a light spring on a horizontal frictionless table . The spring is compressed and then released . Find the ratio of acceleration of masses .

Two blocks of masses m and m' are connected by a light spring on a horizontal frictionless table . The spring is compressed and then released . Find the ratio of acceleration of masses .

Find the mass of the hanging block in which will prevent the smaller block of mass m from slipping over the triangular block of mass M. All the surfaces are frictionless and the strings and the pulleys are light

The bob of a simple pendulum (mass m and length l ) dropped from a horizontal position strikes a block of the same mass elastically placed on a horizontal frictionless table. The K.E. of the block will be
