Answer: kq/r.
- A kq/r
- B kq/r²
- C kqr itself
- D just kq
Correct answer: A. kq/r
Explanation: The potential of a point charge is V = kq/r.
Field lines (radial) and equipotential lines (concentric circles) of a point charge. Equipotential surfaces are always perpendicular to the field lines. Image: Sjlegg, Public Domain, via Wikimedia Commons.
Concept context
