Exam-style question
Try this first
What is the direction of the force between two like charges according to Coulomb's law?.
- A.The force is attractive.
- B.The force is repulsive.
- C.The force is zero.
- D.The force direction cannot be determined.
Model answer
What a good answer should say
- The force is repulsive.
Explanation
Why this works
Coulomb's law states that like charges repel each other, resulting in a repulsive force between them. This is a key characteristic of electric charges.
