A uniform solid cylinder of density
8g/cm3 floats in equilibrium in a combination of two non-mixing liquids A and B with its axis vertical. The densities of liquids A and B are
0.7g/cm3 and
1.2g/cm3, respectively. The height of liquid A is
hA=1.2cm. The length of the part of the cylinder with liquid B is
hB=0.8cm and
h=.2cm. Find the total force exerted by liquid
A on the cylinder:
