Say we have two conductors with length (L = 1.5m) parallel to each other, with currents (I = 15A) that are in opposite directions, and connected by springs on both ends with spring constants (k = 2N/m). When there is no current flowing through the wires, they are a distance l = 0.2m apart, however when the current is flowing through them, they repel each other and stretch the spring by a length d = 0.02m when in equilibrium. The bottom conductor is resting on a surface, while the top conductor is floating above it with a mass (m). a) Draw a free body diagram and label the three forces acting on the top conductor. Make sure that you denote which directions are positive. b) Using Newton's 2nd Law, find the mass of the floating conductor in grams (g). Remember, that when the system is in equilibrium, the floating conductor is not moving, and gravity is 9.8 m/2 k
