Three long, straight wires are seen end-on in the figure below. The distance between the wires is r = 0.258 m. Wires A and B carry current I_A = I_B = 1.54 A, and wire C carries current I_C = 3.30 A. Assume (for example) the only forces exerted on wire A are due to wires B and C. Find the force per unit length exerted on the following. (Express your answers in vector form.)
