In a simple pendulum, work done by the tension force is?
Correct answer: C. Zero
- A. Positive
- B. Negative
- C. Zero
- D. None of these
Explanation
The force is perpendicular to the displacement. Hence, work done is zero.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
