A student proposes to measure the gravitational constant G by suspending two spherical objects from the ceiling of a tall cathedral and measuring the deflection of the cables from the vertical. Draw a free-body diagram of one of the objects. (Do this on paper. Your instructor may ask you to turn in this work.)
If two 130.0 kg objects are suspended at the lower ends of cables 40.00 m long and the cables are attached to the ceiling 1.000 m apart, what is the deflection of each object? (Use 1.000 m for the separation distance in the expression for the gravitational force and assume that the deflection is extremely small compared to 1 m.)
