Charges −q and +q location at A and B, respectively, constitute an electric dipole. Distance AB=2a, o is the midpoint of the dipole and OP is perpendicular to AB. A charge Q is placed at P where OP=y and y2a. The charge Q experiences and electrostatic force F. If Q is now moved along the equatorial line to P’ such that OP’=, the force on Q will be Closed to:
