A pendulum bob is swinging in a vertical plane such that its angular amplitude is less than ${90}^{\circ }$. If at its extreme position, the string is cut, which of the following trajectory is possible for the bob afterwards?

Q. Suppose the amplitude of a simple pendulum having a bob of mass $m$ is ${\theta }_0$. Find the tension in the string when the bob is at its extreme position.

Q.

A bob of mass 0.1 kg hung from the ceiling of a room by a string 2 m long is set into oscillation. The speed of the bob at its mean position is 1 m s^–1. What is the trajectory of the bob if the string is cut when the bob is (a) at one of its extreme positions, (b) at its mean position.

Q. A bob of mass $0.1kg$ hung from the ceiling of a room by a string $2m$ long is set into oscillation. The speed of the bob at its mean position is $1m{s}^{-1}$. What is the trajectory of the bob if the string is cut when the bob is

A at one of its extreme positions

B at its mean position

Q. The length of simple pendulum is $1m$ and mass of its bob is $50gram$. The bob is given sufficient velocity so that the bob describes vertical circle whose radius equal to length of pendulum, the tension in the string at lowest extreme position is:
