Answer: scalar.
- A scalar
- B vector
- C always negative
- D imaginary
Correct answer: A. scalar
Explanation: Potential has magnitude but no direction, so it is a scalar.
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
Electric potential, equipotential surfaces, potential energy of charge systems, conductors, dielectrics, capacitors, combinations, and energy storage.
