A circular cone has a diameter of 100mm and height of 200mm. It was weighed and the result was 1.4N. When it was placed in water, the circular part of the cone was above the surface and the pointed part is at the bottom. Determine the required force to push the cone into the water so that the circular base is exactly at the water surface? (A) F= 4.36 N (B) F= 3.74 N (c) F = 2.51 N D) F= 1.78 N

EMERGENCY!!!! The cover in the figure is hinged at the center O and has a fixed width w = 5 m. The equation of the surface is x = y2 / a (a = 3 m), the depth of the water to the right of the lid (D = 4 m). If the weight of the lid is neglected, it is necessary to keep the lid in balance. Find the size of the force (Fa) required, as shown. Take the density of the water as 999 kg / m3.
