In the diagram, the shaded region shows a uniform electric field pointing away from the observer (that is, at right angles into the plane of the paper). A horizontal beam of electrons enters the field, moving from left to right. In which direction does this beam get deflected by the field?
- Aupwards (in the plane of the paper)
- Bdownwards (in the plane of the paper)
- Caway from the observer
- Dtowards the observer
