When a body is whirled in a horizontal circle by means of a string, the centripetal force is supplied by
Correct answer: C. tension in the string
- A. Mass of the body
- B. velocity of the body
- C. tension in the string
- D. centripetal acceleration
Explanation
The centripetal force required to keep an object moving in a circular path is provided by tension in the string, directed towards the center of the circle.

About Newton's Laws of Motion
Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
