Question 1
What does the superposition principle state regarding electric fields?
- A) Only the greatest field matters.
- B) The total field is the sum of all individual fields.
- C) Electric fields do not interact.
- D) Fields cancel each other out.
💡 Hint: Think about summing effects rather than just looking at the strongest one.
Question 2
True or False: A negative charge produces an electric field that points away from it.
- True
- False
💡 Hint: Consider how the direction of force applies to test charges.

Challenge Problems
Push your limits with challenges.
Question 1
Three charges are arranged: +3μC at (0,0), -2μC at (1,0), and +1μC at (0,1). Calculate the total electric field vector at (0,0.5).
💡 Hint: Consider both horizontal and vertical components in your calculations.
Question 2
A positive test charge experiences forces due to two other charges. If the distance from both charges to the test charge is equal, how do their fields compare if one is positive and the other is negative?
💡 Hint: Draw a diagram to visualize the forces acting on the test charge.
