![The drawing shows two long, straight
wires that are suspended from a ceiling.
The mass per unit length of each wire is
0.047 kg/m. Each of the four strings
suspending the wires has a length of 1.2 m.
When the wires carry identical currents in
opposite directions, the angle between
the strings holding the two wires is 15°.
