Exam-style question
Try this first
A uniform electric field is most likely to be found between the plates of a large parallel‑plate capacitor. Which feature of this field pattern is correct?.
- A.Field lines are radial and diverge from the positive plate
- B.Field lines are uniform and parallel between the plates
- C.Field lines form closed loops around each plate
- D.Field lines are radial and converge on the negative plate
Model answer
What a good answer should say
- Field lines are uniform and parallel between the plates
Explanation
Why this works
Define both: Uniform fields have straight, parallel lines; radial fields have lines that spread from a point. Identify key difference: Between capacitor plates the field does not change direction with position, unlike a radial field.
Explain when each applies: The large, flat plates create a nearly uniform field; a point charge would create a radial field. Conclude: The correct description is that the field lines are uniform and parallel.
