Question

Assertion: In circular motion, the centripetal and centrifugal forces acting in opposite direction balance each other.

Reason: Centripetal and centrifugal forces don’t act at the same time.

(A) Assertion is True, Reason is True; Reason is a correct explanation for Assertion 

(B) Assertion is True, Reason is True; Reason is not a correct explanation for Assertion 

(C) Assertion is True, Reason is False 

(D) Assertion is False but Reason is True.

Answer 1

Answer is (D) Assertion is False but Reason is True.

While moving along a circle, the body has a constant tendency to regain its natural straight line path. 

This tendency gives rise to a force called centrifugal force. The centrifugal force does not act on the body in motion, the only force acting on the body in motion is centripetal force. The centrifugal force acts on the source of centripetal force to displace it radially outward from centre of the path.
