A loudspeaker of mass 18.0 {rm kg} is suspended a distance of h = 1.20 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 2.70 {rm m}. What is the tension T in each of the cables? Use 9.80 {rm m/s}^2 for the magnitude of the acceleration due to gravity
