Identify the correct statements regarding hydrostatic forces on submerged curved surfaces. More than one answer may be correct.

The hydrostatic force acting on a circular surface always passes through the center of the circle.

If the curved surface is above the liquid, the weight of the liquid and the vertical component of the hydrostatic force act in the same directions.

The magnitude of the resultant hydrostatic force acting on the curved surface is $F_R=\sqrt[\phantom{2}]{F_H^2+F_V}{?}^2.$

The angle made with the horizontal by the resultant force is given by $sin=\frac{F_V}{F_H}.$
