Relationship E_p = Vq
What Relationship E_p = Vq means in Physics A-Level, as defined for OCR.
Definition of Relationship E_p = Vq
Check what you remember
Read the wording for your board, then hide it and explain Relationship E_p = Vq in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Using E_p = Vq and substituting V = Q/(4πε₀r) gives E_p = Qq/(4πε₀r).
