The mass of a pendulum bob is 0.2kg, and it is suspended by a string 1m long. It is pulled aside until the thread is at `30^(@)` to the vertical. How much work is done ? The ball is now released. Find its K.E. at the lowest point ? Take `g=10ms^(-2).`

A body of mass 1 kg is suspended by means of a string. It is then pulled aside by a horizontal force so that the string makes an angle of 30^(@) with the vertical. Find the horizontal force.

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 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?

Mass of the bob of a pendulum is 100g and the length of the string is 1m . The bob is initially held is such a way that the string is horizontal . The bob is then released. Find the kinetic energy of the bob when the string makes an angle of (ii) 30^@ with the vertical .

Mass of the bob of a pendulum is 100g and the length of the string is 1m . The bob is initially held is such a way that the string is horizontal . The bob is then released. Find the kinetic energy of the bob when the string makes an angle of (i) 0^@ with vertical
