A ball floats on the surface of water in a container exposed to the atmosphere. When the container is covered and the air is partially removed, then the ball
- A rises
- B gets immersed more in water
- C remains immersed at its former depth
- D may rise or sink
Answer & Solution
Correct Answer
(B) gets immersed more in water
Step-by-step Solution
Detailed explanation
In the given situation, the weight of the ball is supported by the buoyant force of water and buoyant force due to air. As the density of air becomes less, the buoyant force due to the air becomes less. Therefore, to compensate a greater buoyant force due to water is required…
