A few electric field lines corresponding to a particular electric field are illustrated in the figure. The diagram implies that
Options
- A
- B
- C
- D
Correct answer
B.
Step-by-step solution
The magnitude of an electric field at a given point is directly proportional to the density (closeness) of the electric field lines in the vicinity of that point.
From the given diagram, it is clearly visible that the electric field lines are crowded (closer to each other) at points A and C. In contrast, the field lines are spread further apart at point B.
This indicates that the electric field is stronger at points A and C than at point B. Furthermore, the spacing of the field lines at point A is identical to the spacing at point C, which implies that the electric field strengths at these two points are equal.
Therefore, the relationship between the magnitudes of the electric field at these points is .
