Exam-style question
Try this first
A charge of +2 µC is placed in an electric field created by a charge of +4 µC located 0.5 m away. Determine the direction of the force acting on the +2 µC charge.
Model answer
What a good answer should say
- The force acting on the +2 µC charge is directed away from the +4 µC charge.
Explanation
Why this works
This answer is strong because it accurately reflects that like charges repel each other, leading to a force direction away from the source charge. The question assesses the ability to apply Coulomb's law to determine force direction between like charges.
