Problem A1:
Consider the U-shaped tube shown below. The tube contains two different fluids,
one in the left column with a density ρ2 and one in the right column
with a density ρ1. The fluid in the left column is a height
n2 above the bottom piece, and the fluid in the right column is
n1 above the left fluid (ρ2). The area of the
left column is A0, and the area of the right column is
2A0. If the ratio of densities
ρ2 / ρ1 = n3, what is
n3?
