Question

Which equation represents the equilibrium between two liquid columns in a U-shaped tube and why?

Accepted Answer

ρ1h1 = ρ2h2, as it balances the pressure exerted by both liquids.

Answer

ρ1/ρ2 = h1/h2, as it equates the volume of liquids.

Answer

ρ1 + ρ2 = h1 + h2, as it calculates total density.

Answer

ρ1h1 - ρ2h2 = 0, as it measures density differences.
