The first infinite line resides in the x y plane parallel to the x axis, intersecting the y axis at y equals 2. It is labeled, rho l sub 1 equals 1 left parenthesis n centimeters right parenthesis. The second infinite line resides in the y z plane parallel to the y axis, intersecting the z axis at z equals 6. It is labeled, rho l sub 2 equals negative 2 left parenthesis n centimeter right parenthesis. An electric field E starts from the origin and directs straight in the x z plane. E sub 1 passes between vector E and the x axis. E sub 1 equals negative y caret 9. E sub 2 passes through the z axis. E sub 2 equals z caret 6. An electric field r sub 1 caret starts from point 2 m on the y axis and directs leftward. An electric field r sub 2 caret starts from point 6 m on the z axis and directs downward.
