Important Questions on Circular Motion
On a train moving along east with a constant speed , a boy revolves a bob with string of length on smooth surface of train, with equal constant speed relative to train. Mark the correct option(s).

Consider the figure shown below. A block is kept on a rotating rough table over which a man stands. Another man stands on the ground. Choose the correct option(s).

One end of a light inextensible string of length is attached to a particle of mass resting on a smooth horizontal table. The string passes through a smooth hole in the table and its other end is attached to a small particle of same mass. The system is set in rotation as shown in figure with constant angular speed. Choose the correct option(s).

A bob of mass hangs by a light inextensible string which is connected with a rigid support after passing over a smooth pulley . If the bob is released from an angular position , then


A force of constant of magnitude acts on a particle (mass ) moving in a plane such that it is always perpendicular to the velocity of the body. Select the correct option(s).

A bead of mass can slide without friction on a fixed vertical loop of radius . The bead moves under the combined effect of gravity and a spring with spring constant only. The spring is rigidly attached to the bottom of the loop. Assume that the natural length of spring is zero. The bead is released from rest at with non-zero but negligible speed to the bead. The gravitational acceleration is directed downward as shown in the figure. Now choose the correct option(s). (Neglect any type of friction between any contact) (given )

A weightless rod of length carries two equal masses . One is tied at end and other at middle of rod . The rod can rotate in vertical plane about a fixed horizontal axis passing through .
The rod is released from rest in horizontal position. Then, which of the following option(s) is/are correct?
