Dynamics of Circular Motion: Practice Problem & Solution

Short Solution (Best for NEET):

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

Concept: Understanding apparent forces in a non-inertial rotating frame of reference.
Solution: When milk is churned, the denser skim milk experiences a larger centripetal force and moves towards the outer edge, while the less dense cream moves towards the center of rotation due to centrifugal force. Thus, they separate.
