Question
What field pattern can be produced by two point charges?
Markscheme
D
Examiners report
The statistics suggest that many candidates were confused by this question. Field lines have to start and finish on a charge which means that only A and B could be correct if only two point charges are present. But the field lines will be in the same direction on leaving a charge, hence D is the only sensible solution.
