Shown below 1s an electric dipole with equal charges +Q and-Q separated by a distance d. The dipole is free to rotate or move. Consider the following information: The dipole sits inside an external electric field with E>0. The dipole does not feel a net torque. The dipole feels a net force in the-x direction. When rotated from its original orientation and released, the dipole moves back towards the original orientation. (a) On the picture below, sketch field lines corresponding to an external electric field that is compatible with this description. Do not include the field due to the dipole charges. (b) How would the force and torque on the dipole change if the magnitude of the negative charge was increased, Le. if the charge -Q was made more negative? (Two sentences maximum.)?
