Three light, inextensible strings are tied to the small, light ring, C. Two ends are attached to the ceiling at points A and B, making angles = 36.9o and = 60.0o as shown. The third has a mass m = 2.02 kg hanging from it at point D. The system is in equilibrium. What is the magnitude of the tension, in Newton's in the string AC? (Answer: 9.98 N)
