The tank shown in (Figure 1) is completely filled with a liquid of density ρ. The right face is not permanently attached to the tank but, instead, is held against a rubber seal by the tension in a spring. To prevent leakage, the spring must both pull with sufficient strength and prevent a torque from pushing the bottom of the right face out. The pressure at the top of the tank is p0.

What minimum spring tension is needed?

Express your answer in terms of the variables w h ρ and p0 and constant g
