Correct answer: C. Pseudo force

  • A. Real force
  • B. Friction force
  • C. Pseudo force
  • D. None of these options is correct

Explanation

The centrifugal force is a pseudo-force because if the centripetal force ceased for an object in circular motion, the centrifugal force the body is "feeling" would instantly disappear, and the object would travel tangentially to its line of motion.

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.
