Ask Custom Question

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?
