A semicircular plate with radius 4 m is submerged vertically in water so that the top is 2 m above the surface. Express the hydrostatic force against one side of the plate as an integral and evaluate it. (Round your answer to the nearest whole number. Use 9.8 m/s2 for the acceleration due to gravity. Recall that the mass density of water is 1000 kg/m3.) 2ρg∫ 2 ◻ )dx ≈ ◻ N
