Which one of the following provides centripetal force in a circular motion of the body?
- A
Vertical component of weight
- B
Horizontal component of weight
- C
Weight of the body
- D
Force of friction
In circular motion (like a car turning on a flat road), the centripetal force that keeps the body moving in a circle is provided by the horizontal force directed towards the center. On a flat surface, this force is the force of friction between the tires and the road.
Vertical component of weight → balances normal force (acts vertically).
Horizontal component of weight → appears only on a banked track, not on a flat one.
Weight → acts downward, not toward the center.
