In terms of the dimensions shown in Figure 4.71, what is the
pressure on the bottom surface of the container (area = _ R2)?
What is the pressure on the ledge-surface in Figure 4.71? Check whether all of
the force due to gravity on the liquid in the container is accounted for by the
pressure on these two surfaces.
