Suspended parallel wires
Suspended parallel wires#
Two long, parallel wires are hung by cords of length \(s = \) 4.4 \(\rm\ cm\), as shown in the figure. Each wire has a mass per unit length of 38.6 \(\rm\ g/m\), and they carry the same current in opposite directions.
What is the current if the cords hang at \(\theta =\) 3.0\(^\circ\) with respect to the vertical?
