Find the hydrostatic force experienced by the vertically submerged plate. The dashed line segment indicates the water level. (a) A plate whose shape is a half disk of radius 2 meters is vertically submerged in water. Find the hydrostatic force experienced by the plate. (b) A plate whose shape is an equilateral triangle whose side length is 2 m is vertically submerged in water partially. The coordinate system is already set up for you. Find the hydrostatic force experienced by the plate.
