A closed U-shaped tube contains a stationary liquid of density ρ. One side of the tube contains a gas at pressure p₁ and the other side contains a gas at pressure p₂, as shown. The acceleration of free fall is g. Which equation is correct?
- Ap₁ = ρgy
- Bp₂ = ρg(x − z)
- Cp₁ − p₂ = ρg(y − z)
- Dp₁ + p₂ = ρgx
