A uniform solid cylinder of density 0.8g/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. The cylinder is depressed in such a way that its top surface is just below the upper surface of liquid
A and is then released. The acceleration of the cylinder immediately just after it is released is given as
x3m/s2. Find
