It is one question, please help with all. A magnet of mass 3.03 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 = 134.8 N. At what angle theta with respect to the vertical does the magnet hang? 12.4 degrees 63.0 degrees 30.2 degrees 77.6 degrees Consider the same situation as in the previous problem. This time the magnet has mass 6.94 kg and the force pulling the magnet to the right has magnitude 116.9 N. What is the magnitude of the tension force in the cord? 163.7 N 135.3 N 185.0 N 224.2 N Same situation as in the previous two problems this time the magnet s mass is 5.69 kg and the magnetic force pulling it to the right is 154.7 N. The length of the cord is 1.31 m, and the ceiling is 2.63 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 154.7 N. How long will it take the magnet to hit the floor? 0.420 s 0.667 s 0.400 s 1.001 s Same situation as in the previous problem this time the magnet has mass 3.35 kg, the force pulling it to the right is 114.2 N, the cord has length 1.32 m and the ceiling is 2.62 m above the floor. How far to the right of its start point will the magnet have traveled when it hits the floor after the cord is cut? 10.98 m 7.84 m 6.27 m 9.41 m OK, one more time. This time the magnet has mass 6.18 kg and the force pulling it to the right is 129.2 N. When the magnet hits the floor, it continues being pulled to the right by the same magnetic force as before. The coefficient of kinetic friction between the magnet and the floor is 0.332. What will the magnet s acceleration be as it slides to the right along the floor? (Assume static friction is overcome and the magnet will slide.) 17.65 m/s^2 14.12 m/s^2 21.18 m/s^2 10.6 m/s^2
