Electrifying Electrostatics Quiz

• The magnitude of the electrostatic force of attraction or repulsion between two point charges is inversely proportional to the square of the distance between them.
• The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the square of the distance between them.
