Question
State the amount of work done by an object when it moves in a circular path for one complete rotation. Give a reason to justify your answer.
✓
Answer
Amount of work done is equal to zero.
Work is said to be done only when there is displacement produced. In the case of a body moving in a circular path, the body comes to its original place, therefore, there is no displacement, and hence work is zero.
