A sphere is attached by a metal wire to the horizontal surface at the bottom of a river, as shown in Fig. 2.1. 68° direction of flow of water wire sphere water horizontal surface Fig. 2.1 (not to scale) The sphere is fully submerged and in equilibrium, with the wire at an angle of 68° to the horizontal surface. The weight of the sphere is 32 N. The upthrust acting on the sphere is 280 N. The density of the water is 1.0 × 103 kg m–3. Assume that the force on the sphere due to the water flow is in a horizontal direction.
