A bob of mass `m` attached with a string of length `l` tied to a point on ceiling is released from a position when its string is horizontal. At the bottom most point of its motion, an identical mass `m` gently stuck to it. Find the maximum angle from the vertical to which it rotates.

A ball A of mass m attached to a string of length L is released when the string is horizontal. It strikes another ball B of mass 2 m suspended to another string of length L at rest as shown. Find the maximum angle made by the string if the collision is completely inelastic.

A stone of mass m is tied to a string of length l and rotated in a circle with a constant speed v . If the string is released, the stone flies

A simple pendulam of length .l. carries a bob of mass .m.. The bob is released from horizontal position. The tension in the string at t he lowest point would be

Two balls of mass m and 2m are attached with strings of length 2L and L respectively. They are released from horizontal position. Find ratio of tensions in the string when the acceleration of both is only in vertical direction :

A bob of mass m is connected by string of length L to point P. The system is released from rest with the pendulum bob in a horizontal position. Which of the following graph is correctly showing the variation of T (tension) with Ɵ?

A mass is attached to the end of a string of length l which is tied to a fixed point O. The mass is released from the initial horizontal position of the string. Below the point O at what minimum distance a peg P should be fixed so that the mass turns about P and can describe a complete circle in the vertical plane?
