A freely rotating pulley of radius R is shown in the figure below. On the right side of the pulley hangs a body whose weight is three times the weight of the body hanging to its left. Show that the tension that must be exerted on the string for the system to be in equilibrium must be equal to twice the weight of the body to the left.
