A loudspeaker of mass 22.0 {rm kg} is suspended a distance of h = 1.60 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.90 {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.
