An electric dipole (two charges of equal magnitudes and opposite polarities) is oriented along the y axis as shown in the  figure below. You are not told which charge is positive but you know the electric field at a point P on the y axis is as shown by the green arrow on the figure. If the bottom charge is removed, which of the following best describes what happens to the electric field at point P?
