![]() ![]() 2.6 as downward pointing arrows, indicating the gravitational force is pulling down on the cubes. Gravitational force is represented in Fig. These arrows are the same length for each of the cubes, indicating that the strength of the buoyant force acting on each cube is the same.īecause the masses of the cubes are not equal, the gravitational force (G) acting on each cube is different. 2.6 as upward pointing arrows, indicating the water is pushing up on the cubes. By Archimedes’ Principle, the buoyant force (B) acting on each cube is equal. Because the cubes are identical in volume, they displace the same amount of water. Three cubes of the same size, but with different masses and thus different densities, are placed in three beakers of water (Fig.
