F_{1}> F_{2}

                                                        F_{net}(towards right)

electric field intensity is more at +q as field lines are closer

V_{2}-V_{1}=-PE_{2}\cos \theta _{2}-\left ( -PE_{1}\cos \theta _{1} \right )

\theta _{1}=\theta _{2}=180^{o}(along givenline )

E_{2}< E_{1}(as it move towards right)

=\left ( +PE_{2} \right )-\left ( +PE_{1} \right )

\therefore \Delta U\Rightarrow Decrease
