A U-shaped tube is filled mostly with water, but some vegetable oil has been added to both sides of the U tube. On the right side of the tube, the depth of oil is 5.00 cm . On the left side of the tube, the depth of the oil is 2.30cm . The density of the water is 1x10^3 kg/m^3, and the density of the vegetable oil is 9.2 X10^2 kg/m^3 .
Find the difference in fluid level between the two sides of the tube?
My book is not helping at all! Please someone!
