Wires A and B carry current IA = Ig = 1.51 A, and wire C carries current Ic = 3.34 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.) O- Z 1 O O B IB r Ic C (a) wire A FA = N/m (b) wire B f B = N/m Submit Answer8.
