Question

A metallic cubic block of length s=3.25cm is held at rest below water (Pw=1.00x10^3kg/m^3) by a hand that applies a force of 2.74N vertically up. The upper face of the block is 3.70 cm below the surface of the water, which in turn is exposed to the atmosphere. a) What is the density of the block? b) Determine the absolute pressure at the bottom face of the block immediately after the hand is removed. Give the result in kPa. Draw a free body diagram.
