A bob of mass m attached to an inextensible string of length I is suspended from a vertical support. The bob rotates in a horizontal circle with an angular speed `omega` red/s about the vertical. About the point of suspension:

A bob of mass m attached to an inextensible string of length l, is suspended from a vertical support. Bob rotates in a horizontal circle with angular speed omega and string makes an angle of theta with the vertical. Find the angular momentum of bob about axis of rotation

A smalll bob attached to a string of length l is suspended from a rigid support and rotates with uniform speed along a circle in a horizontal plane. Let theta be the angle made by the string with the vertical, then the length of a simple pendulum having the same period is

A metal bob of mass 0.6 kg is attached to the end of a string of length 1 m and the bob is whirled in a horizontal circle with a uniform speed of 12 m/s. What is the centripetal force acting on the bob ? If the speed of the bob is 5 m/s calculate the tension in the string.

A pendulum consists of a bob of mass m=0.1 kg and a massless inextensible string of length l=1.0m . It is suspended from a fixed point at height h=0.9m above a frictionless horizontal floor. Initially, the bob of the pendulum is lying on the floor at rest vertically below the point of suspension. A horizontal impulse P=02.kg-m//s is imparted to the bob lifts off the floor. The magnitude of the angular momentum of the pendulum about the point of suspension just before the bob lifts off is J kg- m^2//s . The kinetic energy of the pendulum just after the lift-off js K Joules. The value of J is ___
