Determine the resultant force acting on the $\backslash (0\mathrm{.}7-\backslash$mathrm$\{$m$\}\backslash )-$high and $\backslash (0\mathrm{.}7-\backslash$mathrm$\{$m$\}\backslash )-$wide triangular gate shown in the figure and its line of action. Take the density of water to be $\backslash (1000\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash ).$ The distance $\backslash ($ d $\backslash )$ from the surface to the top of the gate is $0\mathrm{.}33$ m as shown in the figure.

The resultant force acting on the triangular gate is

N $.$

The line of action of the force is

m $.$
