MCQ
When a body moves in a circular path, no work is done by the force since,
- AThere is no displacement
- BThere is no net force
- ✓Force and displacement are perpendicular to each other
- DThe force is always away from the centre
✓
Answer
Correct option: C.
Force and displacement are perpendicular to each other
(c) $\because W=F S \cos \theta \quad \therefore \theta=90^{\circ}$
