An electron beam is sent into an electric field and is bent by the field. Diagram 1 shows an electric field in the plane of the paper. Diagram 2 shows an electric field that is perpendicular to the plane of the paper. The lines A, B, C and D show possible routes for the electron beam. Every route lies in the plane of the paper. Which line most accurately shows the route of the electrons within the field?
