TextElectric Field Due to a Dipole on Equatorial LineCBSE PYQ

The distance of a far off point on the equatorial plane of an electric dipole is halved. How will the electric field be affected for the dipole ?

Two identical dipoles are arranged in x-y plane as shown in the figure. Find the magnitude and the direction of net electric field at the origin O.
