Two long heavy duty conducting rods are suspended by non-conducting support ropes as shown below. The rods have a mass per unit length of 47.5 g/m, the support ropes are 5.55 cm long, the rods carry the same current and in such a manner that they repel each other, and the angle between the support ropes is 17.0°. (a) Find the magnitude of the current. A (b) Are the currents in the same direction or in the opposite direction? ◇ in the same direction ◇ in opposite directions (c) If this same arrangement is set on the moon, what current would be required to obtain the same angle between the ropes? You may use 9 Moon = 9 Earth/6. A
