Two iron balls of the same volume – solid and hollow – were immersed in a vessel with water

Two iron balls of the same volume – solid and hollow – were immersed in a vessel with water and released. Are the same or different forces acting on these bodies?

The pushing force of a body immersed in a liquid is proportional to the mass of the liquid displaced by it in the volume of the submerged part of the body. Because two balls are completely immersed in water and they have equal volumes, then the pushing force acting on them is the same, but the hollow ball has less weight and can float if the gravity acting on the ball is less than the buoyancy force. The solid ball will sink.
