6) A 4 m wide tank with an L-shaped cross-section, as shown has a gate which is hinged at point \( A \). If the tank is filled with water to a level of 6 m Determine: The hydrostatic force acting on the gate. The location of the pressure center from the free surface. The magnitude of the minimum force \( F \), applied at \( B \), to keep the gate closed.
