Variation of pressure

From the equation of pressure, pressure is directly proportional to the applied force.

Question

Dallia is in the process of measuring the density of a green oil. She is using a U-shaped tube
filled with blue water. She carefully pours some of the oil in one end of the tube, making sure
they don't mix and letting them settle to a static configuration. She then measures the heights
shown in the figure. She measures h₁ = 2.5 cm, h₂= 3.3 cm, and h3 = 8.2 cm.
A
M₂
What is the density of the oil?
B
Without performing any calculations, compare the pressure at points A and B as marked
in the diagram. Explain your reasoning. (Hint: all the fluids are static at the moment
shown in the diagram.)
What is the gauge pressure at the interface between the oil and the water?
