A uniform solid cylinder of density `0.8g//cm^(3)` floats in equilibrium in a combination of two non mixin liquids `A` and `B` with its axis vertical. The densities of liquids `A` and `B` are `0.7g//cm^/(3)` and `1.2g//cm^(3)`, respectively. The height of liquid `A` is `h_(A)=1.2cm.` The length of the part of the cylinder with liquid `B` is `h_(B)=0.8 cm.`

a. Find the total force exerted by liquid `A` on the cylinder.
Find `h` the length of part of the cylinder in air.
c.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. Find the aceleration of the cylinder immediately just after it is released.
