There are two charges, one is positive and one is negative, but equal in magnitude. they are located near the origin, one slightly in the positive k direction, one slightly in the negative k direction. assume that they are very close, but with a large charge, and that the value of q*x=a, where q is the magnitude of each charge, and x is the distance they each are from the origin. for a given value of a, what is the electric field everywhere? considering the symmetries of the problem, you may want to use a cylindrical coordinate system (that is polar coordinates for the ij plane, and cartesian in the k direction)
