(C) Rings P and R arrive simultaneously, followed by Q to the bottom of the magnet.
The image given in the question is attached below.
Explanation:
- Ring P is plastic (non-metal) in nature. It does not have any magnetic properties. So, the ring will slide the hollow magnet very easily.
- Ring Q is copper which is a metal. When it is made to slide through the hollow magnet. The ring gets attracted by magnet and it takes much longer time to reach the bottom.
- Ring R is also copper but it is broken. It does not form pole. So, when it is made to slide through the magnet. It reaches without any force attracting it towards magnet.
- Thus, Ring P reaches the bottom first with Ring R then Ring Q reaches finally.
