Question: 1 / 400

What happens to the buoyancy force acting on an object as it is submerged deeper in a fluid?

It remains constant regardless of depth

The buoyancy force acting on an object submerged in a fluid is determined by the volume of the fluid that the object displaces and the density of the fluid. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the object.

As an object is submerged deeper into a fluid, the volume of the displaced fluid does not change as long as the volume of the object remains constant. Therefore, the buoyant force remains constant at different depths, as it is directly related to the constant volume of fluid displaced and its density, assuming the fluid’s density itself does not significantly change with depth.

In most cases, especially in incompressible fluids like water, the density remains fairly constant even as the depth increases. This stability in both the volume of fluid displaced and the density results in a constant buoyant force, regardless of how deep the object is submerged.
