A counterweight of mass m = 4.80 kg is attached to a light cord that is wound around a pulley as shown in the figure below. The pulley is a thin hoop of radius R = 6.00 cm and mass M = 2.50 kg. The spokes have negligible mass. m M s i (a) What is the net torque on the system about the axle of the pulley?
