Physics Two Dimensional Motion Question 19
Assertion: In circular motion, the centripetal and centrifugal force acting in opposite direction balance each other. Reason: Centripetal and centrifugal forces do not act at the same time.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.

Answer:
Correct Answer: D
Solution:
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.
