A vertical plate is submerged in water and has the indicated shape. (i) Express the hydrostatic force (in N) against one side of the plate as an integral (let the positive direction be downwards) and evaluate it. (Use 9.8 m/s2 for the acceleration due to gravity. Recall that the weight density of water is 1,000 kg/m3.) ρg∫ 0 9 ( ◻ )dx ≈ ◻ N
