A rectangular plate 0.75m x 2.4 m is immersed in a liquid of relative density 0.85 with its 0.75 m side horizontal and just at the water surface. If the plane of plate makes an angle of 600 with the horizontal, what is the approximate pressure force on one side of the plate?
a. 7.80 kN b. 15.60 kN
c. 18.00 kN d. 24.00 kN
