A point particle of charge Q is located at P along the axis of an electric dipole $\displaystyle 1$ at a distance r as shown in the figure. The point P is also on the equatorial plane of a second electric dipole $\displaystyle 2$ at a distance r . The dipoles are made of opposite charge q separated by a distance $\displaystyle 2 a$. For the charge particle at P not to experience any net force, which of the following correctly describes the situation?
