Question

The work done by a pendulum after a complete oscillation is

• A. zero
• B. equal to potential energy of the pendulum.
• C. equal to kinetic energy of the pendulum
• D. equal to total energy of the pendulum

Answer 1

The correct option is A

zero

1. Work done is the product of force applied and displacement
2. Here displacement is zero.
3. So work also becomes zero.

Hence option(A) is correct
