A uniform rod of length 0.820 m and mass 13.0 kg is balanced on a sharp edge at 0.660 m from the left end. At the left end hangs a mass of 45.0 kg and the right end hangs an unknown mass so that the whole assembly is in equilibrium.
Calculate the torque on the center of mass of the rod alone with respect to the pivot point.
Calculate the unknown mass.
Briefly describe how the resulting interference pattern will differ for the various types of particles passing through: protons, electrons, neutrinos (mass close to zero) and photons. Assume that the distribution of particle energies is the same f..
