The correct Answer is:
To solve the question regarding the assertion and reason about centripetal and centrifugal forces, we will analyze both statements and determine their validity step by step. ### Step 1: Understand the Assertion **Assertion:** Centripetal and centrifugal forces always cancel each other. - **Centripetal Force:** This is a real force that acts on an object moving in a circular path, directed towards the center of the circle. - **Centrifugal Force:** This is often referred to as a pseudo force or imaginary force that appears to act on an object in a rotating frame of reference, directed away from the center of the circle. ### Step 2: Analyze the Assertion - The assertion claims that these two forces cancel each other. However, for two forces to cancel each other, they must act on the same object and be equal in magnitude and opposite in direction. - In this case, the centripetal force is a real force acting on the object, while the centrifugal force is not a real force; it is a perceived force due to the rotation of the reference frame. ### Step 3: Understand the Reason **Reason:** This is because the two forces act on different bodies. - This statement suggests that the centripetal and centrifugal forces act on different bodies, which is incorrect. - Both forces act on the same body (the object in circular motion). The centripetal force pulls the object towards the center, while the centrifugal force is perceived by an observer in the rotating frame. ### Step 4: Conclusion - Since the assertion is false (centripetal and centrifugal forces do not cancel each other) and the reason is also false (they act on the same body), we can conclude that both the assertion and the reason are incorrect. ### Final Answer Both the assertion and the reason are false. ---
