A loudspeaker of mass 25.0 kg is suspended a distance of 1.00 m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of 2.50 m . What is the tension in each of the cables?

  • Physics - ,

    The angles matter.

    SinTheta=1/2 mg /Tension

    solve for tension: tension= mg/2sintheta

  • Physics - ,

    oh, tantheta=1/2.50, so you can get theta from that.

  • Physics - ,

    300

  • Physics - ,

    290

  • Physics - ,

    294
