(i) With reference to the direction of action, how does a centripetal force differ from a centrifugal force during uniform circular motion?
(ii) Is centrifugal force the force of reaction of centripetal force?
(iii) Compare the magnitudes of centripetal and centrifugal force.

Answer
(i) Centripetal force always acts towards the centre of circle along it's radius. It is this force which compels the body to move along the circular path. A centrifugal force appears to act away (outward) from the centre of circular path. Thus, the two forces act in opposite directions.
(ii) No, the centrifugal force is not the force of reaction of centripetal force.
(iii) Centripetal force and centrifugal force have equal magnitudes.
