Definition of Perpendicularity of force and displacement
Check what you remember
Read the wording for your board, then hide it and explain Perpendicularity of force and displacement in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The electric force is always perpendicular to the equipotential surface, so the force has no component along the displacement.
