Three balls with the same radius 19 cm are in water. ball 1 floats, with half of it exposed above the water level. ball 2, with a density 856 kg/m^3 is held below the surface by a cord anchored to the bottom of the container, so that it is fully submerged. ball 3, of density 1297 kg/m^2, is suspended from a rope so that it is fully submerged. assume the density of water is 1000 kg/m^3
