physics help?

Question

a cylinder (mass = 7kg radius=0,15m height = 0,12) is floating in water.

oil is added so that it is floatin between the oil and the water.

i want to know how much of the height of the cylinder is in oil??

method please.Thanks in advance

Answer 1

The method I'd use is express buoyant force for the new scenario (i.e. from both liquids) and set it equal to gravity.

The way you state it is kind of looping to itself or ambigious. It sounds like1/2 of the height is in oil because you added so much oil that it's floating in between oil and water, not more and not less.
