Transcribed Image Text:Three infinite straight wires are fixed in place and aligned parallel to the z-axis
as shown. The wire at (x,y) = (-13 cm, 0) carries current I = 3.2 A in the
negative z-direction. The wire at (x,y) = (13 cm, 0) carries current I2 = 1.4 A in
the positive z-direction. The wire at (x,y) = (0, 22.5 cm) carries current I3 = 5 A
in the positive z-direction.
