In the cavendish balance apparatus suppose that m1100 kg m2, Ask an Expert

Academics

In the Cavendish balance apparatus, suppose that m1=1.00 kg, m2= 20.0 kg, and the rod connecting each of the pairs of masses is 28.0cm long. Once the system reaches equilibrium, each pair of masses, m1 and m2, are separated by a distance of 13.0 cm center to center.

Part A find the magnitude of the net force on one of the small masses, m1

Part B Find the gravitational torque (about the rotation axis) on the rotating part of the apparatus. Ignore any forces on the connecting rods in your calculation

Part C Suggest some ways to improve the sensitivity of the experiment.
