The mass of a simple pendulum bob is 100 gm. The length of the pendulum is 1 m. The bob is drawn aside from the equilibrium position so that the string makes an angle of `60^(@)` with the vertical and let go. The kinetic energy of the bob while crossing its equilibrium position will be

A bob of mass 2 kg hangs from a string of length 5 m . It swings from its rest position to one of the sides so that the string makes an angle of 60^(@) with the vertical Calculate the gain in potential energy of the bob .

A pendulum bob has a speed of 3ms^(-1) at its lowest position. The pendulum is 0.5 m long. The speed of the bob, when string makes an angle of 60^(@) to the vertical is ("take, g"=10ms^(-1))

The bob of a pendulum has its rest point 1 m below the support. The bob is pulled aside until the string makes an angle of 60^@ with the vertical line. On release with what speed does the bob swing pass its rest point?

The bob of a pendulum has its rest point 1 metre below the support. The bob is pulled aside until the string makes an angle of 15^(@) with the vertical. Upon release, with what speed does the bob swing past its rest point ?

The bob of a pendulum of length l is pulled aside from its equilibrium position through an angle theta and then released. The bob will then pass through its equilibrium position with a speed v, where v equals

The bob of pendulum of length l is pulled aside from its equilibrium position through an angle theta and then released. Find the speed v with which the bob passes through the equilibrium position.

A nail is located at a certain distance vertically below the point of suspension of a simple pendulum. The pendulum bob is released from a position where the string makes an angle of 60^(@) with the vertical. Calculate the distance of nail from the point of suspension such that the bob will just perform revolutions with the nail as centre. Assume the length of the pendulum to be one meter.

In a simple pendulum, the breaking strength of the string is double the weight of the bob. The bob is released from rest when the string is horizontal. The string breaks when it makes an angle theta with the vertical.
