Centripetal and Centrifugal Forces – Rankers Physics

Uniform Circular Motion: Practice Problem & Solution

Assertion (A): In circular motion, centripetal and centrifugal forces act in opposite directions and balance each other. Reason (R): Centripetal force is a pseudo force.  
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false

Solution Explained:

To solve this problem, we apply the core principles of Uniform Circular Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Centripetal force is a real force causing circular motion. Centrifugal force is a pseudo force in a non-inertial frame. They are not interaction pairs and do not balance each other. So (A) is false. Centripetal force is a real force. So (R) is false.
