EXERCISE 4A metal body in the shape of a rectangular parallel epiped with dimensions 12.0cm by 10.0 cm by 10.0 cm and mass 10.0 kg is hung on a scale and immersed in water, as shown in the picture. The dimension of 12.0 cm is vertical, and the upper seat of the body is 5.00 cm below the surface of the water, (a) What are the measures of the forces exerted on the upper and lower seat of the body by the water that surrounds it? (b) What is the indication of the scales? (c) Show that the buoyancy force is equal to the difference of the forces exerted on the upper and lower seats.
