An electric dipole is the combination of two equal and opposite charges q and -q, respectively, separated by distance 2a. There are different points where we can find electric field due to the electric dipole. In the given table, column 1 shows different positions of point where we have to find electric field due to dipole, column 2 shows the figure of dipole with different positions of point where we have to find the electric field and column 3 shows the value or final formula of the electric field of different positions of the point.
when point P lies on the equatorial plane of the electric dipole, electric field due to +q is ?
