80. (a) We designate the wire along y = r A = 0.100 m wire A and the wire along y = r B = 0.050 m wire B . Using Eq. 29-4, we have 6 00 net ˆˆ ˆ k k ( 52.0 10 T)k. 22 AB ii BB B rr µ =+= = × G GG ππ (b) This will occur for some value r B < y < r A such that i ry i yr A A B B = b g b g . Solving, we find y = 13/160 0.0813 m.
