A positively-charged particle is projected into a uniform electric field. Which diagram represents the path of the particle in the electric field?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
ADiagram showing parallel downward electric field lines and a positive particle curving downwards.
BDiagram showing parallel downward electric field lines and a positive particle moving straight downwards.
CDiagram showing electric field lines into the paper (X symbols) and a positive particle curving downwards in the plane of the paper.
DDiagram showing electric field lines into the paper (X symbols) and a positive particle moving horizontally, then curving slightly downwards in the plane of the paper.
✓ Correct answer
A: Diagram showing parallel downward electric field lines and a positive particle curving downwards.
