In the arrangement shown in Fig. 1, each of the two long, parallel conductors carries a current I, is supported by 8-cm-long strings, and has a mass per unit length of 0.3 g/cm. Due to the repulsive force acting on the conductors, the angle θ between the supporting strings is 10°. Determine the magnitude of I and the relative directions of the currents in the two conductors.
