9702Electric fields and field lines
A flat plate is positively charged and a curved plate is negatively charged. Which diagram shows the electric field lines between the two plates?
- ADiagram A: field lines pointing downward from the flat positive plate to the curved negative plate, perpendicular to both plates
- BDiagram B: field lines pointing upward from the curved negative plate to the flat positive plate, perpendicular to both plates
- CDiagram C: field lines pointing downward from the flat positive plate to the curved negative plate, perpendicular to the flat plate but not to the curved plate
- DDiagram D: field lines pointing upward from the curved negative plate to the flat positive plate, perpendicular to the flat plate but not to the curved plate
