In the above figure if applied electric field is at angle(but not normal) to the surface and is limited only to a specific region as shown, I believe the Electric field due to the induced charges will be in opposite direction of the applied electric field as shown by dotted lines.

In the above two diagrams, electric field is present everywhere but at an angle(but not normal) to the surface as shown. I don't know(direction of induced electric field)if fig.2 is correct or fig.3. I don't understand if the induced electric field will oppose the applied electric field in opposite direction so that there is a possibility of reducing the potential energy as shown in fig.2 or if induced electric field will follow "least action path" to oppose the applied electric field as shown in fig.3 ? 

Please help me understand.
