Solved: Cavendish Experiment. In the Cavendish balance
Chapter 13, Problem 13.2(choose chapter or problem)
Cavendish Experiment. In the Cavendish balance apparatus shown in Fig. 13.4, suppose that m1 = 1.10 kg, m2 = 25.0 kg, and the rod connecting the m1 pairs is 30.0 cm long. If, in each pair, m1 and m2 are 12.0 cm apart center to center, find (a) the net force and (b) the net torque (about the rotation axis) on the rotating part of the apparatus. (c) Does it seem that the torque in part (b) would be enough to easily rotate the rod? Suggest some ways to improve the sensitivity of this experiment
