There are two wires of length 5m parallel to each other, 3 meters apart. The plane created by the two wires is normal to the vector from the center of earth to the center of gravity of the system. The currents in both wires is in the same direction, 5 A. The wires are in equilibrium, each held in place; each wire can be treated as a rigid rod. At the instant the wires are let go, what is the magnitude of acceleration of either wire?

Maybe I'm missing something, but you must have some way of determining the mass of the wires.
