Imagine That the tank is filled with water. The height of the liquid Collin is 7 m and the area is 1.5 m² what's the force of gravity acting on the column of water

= = The volume of water in the tank is (1.5 m²) x (7 m) = 10.5 m³.

= = The density of water is 1000 kg / m³.

= = The mass of water in the tank is (10.5 m³) x (1000 kg/m³) = 10,500 kg.

= = The force of gravity is (mass?) x (gravity)

force = (10,500 kg) x (9.8 m/s²)

force = 102,900 Newtons
