Textbook Problem

Two long, parallel wires, each with a mass per unit length of 0.040 kg/m, are supported in a horizontal plane by 6.0-cm-long strings, as shown in Figure P19.72. Each wire carries the same current I, causing the wires to repel each other so that the angle θ between the supporting strings is 16°. (a) Are the currents in the same or opposite directions? (b) Determine the magnitude of each current. a)

To determine
Whether the current in the two wires are in same or opposite direction.

Explanation

Given info: The mass per unit length of the two wires is 0.040kgm-1 . The length of the string by which the wires are suspended is 6.0cm . The magnitude of the current in both the wires is same. The angle between the suspending string is 16°

b)

To determine
The magnitude of the current in the wires.
