Using Coulomb's law, electric field is computed at every grid in a 2-D plane.
There are 100 grids in both x and y direction, each grid measuring 1 meter in length. The axis are manipulated in such a way that the center of the figure appears to be the Cartesian coordinates origin, (x,y) = (0,0). The dipole charge is 1 nC, while the dipole length is 10 meters(10 grids apart).
