If a weighted air-filled balloon sinks in deep water, it will

B)likely burst if water pressure is great enough.
C)be acted on by a continuously decreasing buoyant force.
D)none of the above

Question

Quizplus · Accepted Answer

When a weighted air-filled balloon sinks in deep water, it will experience an increasing water pressure with depth, and the air inside will compress, leading to a corresponding decrease in volume. This decrease in volume will shrink the balloon's size and its displacement in water, resulting in a continuously decreasing buoyant force acting on it. Therefore, option C is the correct choice. Option A is partly correct, as the balloon will stop sinking once the buoyant force becomes equal to the force of gravity, but it may not necessarily be at an equilibrium level. Option B is incorrect as the balloon is filled with air and not water, and hence, will not burst due to water pressure. Option D is incorrect as some of the options are correct.
