Question 3: Consider a solid square block with constant density p, and sides of length L at the bottom of a pool of depth H filled with water of constant density p (see Figure 1). There is no fluid between the bottom of the block and pool floor.Determine the pressure field in the water assuming the air above the pool has pressure p0. Determine the force exerted by the block on the pool floor. Describe why the result is physically sensible.
