In each electric field diagram, a positively charged particle is moved from X to Y. In which diagram would the particle experience an increasing repulsive force?

Q: What topic does this question test?

This question tests Electric fields in A-Level Physics (syllabus code 9702). It is worth 1 mark.

AElectric field lines diverging from a point; X is further from the origin of divergence, Y is closer.

BElectric field lines diverging from a point; X is closer to the origin of divergence, Y is further.

CUniform vertical electric field with X on one line and Y on an adjacent line at the same vertical level.

DUniform vertical electric field with X and Y at different vertical levels on different field lines.

✓ Correct Answer

The correct answer is B: Electric field lines diverging from a point; X is closer to the origin of divergence, Y is further.
