Problem #3 An open tank has a vertical partition separating two fluids: gasoline and water. The height of gasoline is \( 4 m \) and height of water is \( h \). The partition has a massless gate with width of \( 2 m \) and height of \( f \) \( m \). Water is added to the other side of the tank. At what water level \( h \) will the gate start to swing toward the gasoline side?
