Three balls are in water. Ball 1 floats, with half of it exposed above the water level. Ball 2, with a density less than the density of water is held below the surface by a cord anchored to the bottom of the container, so that it is fully submerged. Ball 3, of same radius as ball 2, but of greater mass, is suspended from a rope so that it is fully submerged. Part (a) Which is true for Ball 1? 1. The magnitude of the buoyancy force is less than that of the ball's weight 2. The magnitude of the buoyancy force is more than that of the ball's weight. 3. The magnitude of the buoyancy force is equal to that of the ball's weight. 4. The magnitude of the buoyancy force is exactly one half of that of the ball's weight. Part (b) Which is true for Ball 2? Part (c) Consider Ball 2 and Ball 3. Which one experiences the larger buoyancy force?
