Calculate the fluid force (in Newtons) on one side of a square plate that is submerged in water at a horizontal angle of $30^{\circ}$. The side of the plate is 3 m long. Assume that the top edge of the plate lies at a depth of 2 m and $g = 9.8\text {m/s}^2$. The density of water is 9800 N/m$^3$.

$F=$ N
