MCQ
When a body moves in a circular path, no work is done by the force since,
  • A
    There is no displacement
  • B
    There is no net force
  • ✓
    Force and displacement are perpendicular to each other
  • D
    The force is always away from the centre
✓

Answer

Correct option: C.
Force and displacement are perpendicular to each other
(c) $\because W=F S \cos \theta \quad \therefore \theta=90^{\circ}$
