A small cylinder of uniform density 0.95g/cm3 is gently placed into a vertical tank containing two immiscible liquids. The top layer is oil of density 0.80g/cm3, and the bottom layer is salt water of density 1.05g/cm3. After the cylinder comes to rest, where will it be located?
(a) Floating at the interface, with about 40% of its volume in oil and 60% in salt water
(b) Resting on the bottom of the tank, fully immersed in the salt water
(c) Floating entirely on the top surface of the oil layer
(d) Fully submerged in the salt water layer, hovering just below the interface
