Two weights are connected by a very light, flexible cord that passes over an 80.0 NN frictionless pulley of radius 0.300 mm. The pulley is a solid uniform disk and is supported by a hook connected to the ceiling (Figure 1). What force does the ceiling exert on the hook? Express your answer with the appropriate units.
