The work done by the string of a simple pendulum during one complete oscillation is

The work done by the string of a simple pendulum in one complete oscillation is equal to

The work done by the tension in the strings of a simple pendulum in one complete oscillation is equal to

(A): The work done by the tension in the string of a simple pendulum in one complete oscillation is zero (R): No work is done by the tension in the string since tension is always at right angles to the motion of the body in case of simple pendulum.

Workdone by a simple pendulum in one complete oscillation is ..........
