What does Coulomb's law state about the force between two point charges?.
Model answer
What a good answer should say
- Coulomb's law states that the force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.
Explanation
Why this works
This answer is strong because it accurately describes the relationship defined by Coulomb's law, which is fundamental in understanding electric forces. The question tests the student's recall of a key physics principle related to electric fields.
