Question

A balloon filled with some liquid is inflated and immersed under water. The balloon remains at rest under water. What would happen if the volume of the balloon decreased while the mass remained the same?

Responses

The balloon would float and accelerate upwards because there would be a greater buoyant force acting on it than before.

The balloon would sink and accelerate downwards because there would be a smaller buoyant force acting on it than before.

The balloon would remain at rest because the mass stays the same and so the forces on the balloon would not change.

The balloon would float and accelerate upwards because the smaller volume means it would take less force to make it float.

Answer 1
