Two long, straight conducting wires with linear mass density lambda are suspended from cords so that they are each horizontal, parallel to each other, and a distance d apart. The back ends of the wires are connected to one another by a slack, low-resistance connecting wire. A charged capacitor (capacitance C) is now added to the system; the positive plate of the capacitor (initial charge + Q_{0} ) is connected to the front end of one of the wires, and the negative plate of the capacitor (initial charge - Q_{0} ) is connected to the front end of the other wire (see the figure ). Both of these connections are also made by slack, low-resistance wires. When the connection is made, the wires are pushed aside by the repulsive force between the wires, and each wire has an initial horizontal velocity of magnitude v_0. Assume that the time for the capacitor to discharge is negligible compared to the time it takes for any appreciable displacement in the position of the wires to occur.
