Problem

A 10 kg10\,\text{kg} mass is suspended from the ceiling by two light strings. One string makes an angle of 30∘30^{\circ} with the horizontal and the other makes 60∘60^{\circ} with the horizontal. The system is at rest. What is the tension in the string that makes 30∘30^{\circ} with the horizontal? (Take g=9.8 m s−2g = 9.8\,\text{m s}^{-2}.) (a) 85 N85\,\text{N} (b) 49 N49\,\text{N} (c) 56 N56\,\text{N} (d) 72 N72\,\text{N}
