An infinitely long, uniformly charged straight line has linear
charge density ?1 coul/m. A straight rod of length 'b' lies in the
plane of the straight line and perpendicular to it, with its enared
end at distance 'a' from the line. The charge density on the rod
varies with distance 'y', measured from the lower end, according to
