Simple Pendulum - Tension in the string

A simple pendulum having a bob of mass m undergoes small oscillations. If theta is the small angle that makes with the vertical at the extreme positions, find the tension in the string as a function of the angle made by the string with the vertical. When is the tension maximum and when it is a minimum?

Suppose the speed of the bob at an angle phi is V. Using conservation of energy between the extreme position and a position with angle phi,(phi < theta), we can ...

Solution Summary

Clear explanations with final answer. We start with the law of conservation of energy.
