The work done by the string of a simple pendulum during one complete oscillation is equal to
-
- Total energy of the pendulum
- Kinetic energy of the pendulum
- Potential energy of the pendulum
- Zero
- Total energy of the pendulum
Correct Option: D
Work done by the string of the simple pendulum during one complete oscillation is zero. Tension in the string exactly cancels the component parallel to the string. This leaves a net restoring force back toward the equilibrium position as equal to zero.
