An electric dipole coincides on z axis and its mid point is on origin of the cartesian co-ordinate system. The electric field at an axial point at a distance z from origin is `vecE`(z) and electric field at an equatorial point at a distance y from origin is `vecE(y) |vecE_((z))/vec E_((y))| (y = z > > a) =`
