Assertion: Cream gets separated out of milk when it is churned due to gravitational force. Reason: In circular motion, gravitational force is equal to centripetal force.

1. If both assertion and reason are true and the reason is the correct explanation of the assertion.
2. If both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. If the assertion is true but the reason is false.
4. If the assertion and reason both are false.

Correct answer: If the assertion and reason both are false.

Solution

Cream separates from milk during churning due to centrifugal effect in the rotating frame, not due to gravitational force. Also, gravitational force is not generally equal to centripetal force; centripetal force is the net inward force required for circular motion.
