Exam-style question
Try this first
Determine the direction of the force between two point charges, +3 µC and -2 µC, when they are placed 0.5 m apart.
Model answer
What a good answer should say
- The force between the positive charge (+3 µC) and the negative charge (-2 µC) will be attractive, meaning the force will act towards each other.
Explanation
Why this works
This answer is strong as it correctly identifies the nature of the force between unlike charges, which is fundamental to understanding electric interactions. The question assesses the student's ability to apply knowledge of charge interactions to determine force direction.
