1. A magnet of mass 4.44 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 = 65.3 N. At what angle theta ?with respect to the vertical does the magnet hang? 2. Consider the same situation as in the previous problem. This time the magnet has mass 6.75 kg and the force pulling the magnet to the right has magnitude 56.1 N. What is the magnitude of the tension force in the cord? 3. Same situation as in the previous two problems this time the magnet s mass is 4.56 kg and the magnetic force pulling it to the right is 117.2 N. The length of the cord is 1.97 m, and the ceiling is 2.68 m above the floor. Suppose that you cut the cord and the magnet falls to the floor while still being pulled to the right by the force of 117.2 N. How long will it take the magnet to hit the floor?
