Vedclass · Answer

(C) In a simple pendulum,the tension force $T$ in the string always acts towards the point of suspension.As the pendulum bob moves along its circular arc,the displacement vector $ds$ is always tangent to the path.The tension force $T$ is always directed towards the center of the circle,which is perpendicular to the displacement vector $ds$ at every point.Since the work done $W$ is defined by the dot product $W = \int T \cdot ds = \int T \cos(90^{\circ}) ds$,and $\cos(90^{\circ}) = 0$,the work done by the tension is $0$.
