The cross section of a dam wall is an arc of a circle of radius R = 20 m subtending on angle of θ = 60 degree at the centre of the circle. The centre (O) of the circle lies in the water surface. The width of the dam (i.e., dimension perpendicular to the figure) is b = 10 m.

The side wall of a wide vertical vessel of height h = 75 cm has a narrow slit (vertical) running all the way down to the bottom of the vessel. The length of the slit is l = 50 cm and the width is b = 1 mm. With the slit closed, water is filled to the top. Find the resultant reaction force of water coming out
