Electricity and Magnetism urgent!help!

11. Electric charge is distributed uniformly along each side of a square. Each side of the square has length a. Two adjacent sides have positive charge with total charge +Q on each.
(i) If the other two sides have negative charge with total charge –Q on each, what are the x- and y-components of the resultant electric field at the center of the square?
(ii) Repeat the calculation of part (i) if all four sides have positive charge +Q.


12. A point charge is distance from the center of a dipole consisting of charges separated by distance . The charge is located in the plane that bisects the dipole. At this instant, what are (a) the force (magnitude and direction) and (b) the magnitude of the torque on the dipole? You can assume r >> s .
