An electric dipole coincides on Z-axis and its mid point is on origin of the 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) Here, z=y gt gt a, so |vecE_(x)|/|vecE_(y)|=............... |
