What happens with an object when the buoyant force is equal to the force of gravity?

The object will experience no net force and no movement will occur.


What will happen , assuming that the fluid is completely static, is that the object will remain fixed at every position in the fluid. If you placed it 5 meters down in the tank, it would stay at exactly the same height.

A good example of this happening is a plastic bag filled with water. If you put this in a swimming pool or a tub of water, the bag will just hover in place. This is because the buoyant force equals the gravitational force.
