Consider the pulley system below supporting an object with mass m. As- sume gravitational acceleration to be g, that the pulleys are massless and friction- less, and the string is massless and inextensible. With how much force F must the string be pulled to keep the mass at the same height? m force F A mg 3 B mg 2 C D E mg 2mg 3mg [2]
