Force experienced per unit positive test charge at a point in an electric field is the definition of:
Correct answer: B. Electric field strength
- A. Electric potential energy
- B. Electric field strength
- C. Electric potential
- D. Electric field
Explanation
The strength of an electric field E at any point may be defined as the electric, or Coulomb, force F exerted per unit positive electric charge q at that point, or simply E = F/q.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
