A bottle of sodalime is grasped by the neck and swung briskly in a vertical circle, Near which portion of the bottle do the bubbles collect?

Answer & Solution
Correct Answer: Option C
Due to the lightness of the gas bubble they feel less centrifugal force so they get collected near the neck of the bottle. They collect near the center of circular motion i.e. near the neck of the bottle.
