Use the figure to answer the following questions.

 

  1. A magnet of mass 5.58 kg is suspended from the ceiling by a cord as shown. A large magnet is somewhere off to the right, pulling on the small hanging magnet with a constant force of F = 152.5 N. At what angle theta ?with respect to the vertical does the magnet hang?

      a.

    70.3 degrees

      b.

    19.7 degrees

      c.

    54.0 degrees

      d.

    59.0 degrees

  2. Consider the same situation as in the previous problem. This time the magnet has mass 6.70 kg and the force pulling the magnet to the right has magnitude 99.9 N. What is the magnitude of the tension force in the cord?

      a.

    199.6 N

      b.

    292.2 N

      c.

    119.6 N
