Concepts Of Physics MCQ Edition [Volume 2]PhysicsElectric Field and Potential
A few electric field lines corresponding to a particular electric field are illustrated in the figure. The diagram implies that
Options
- AE_A = E_B = E_C
- BE_A = E_C > E_B
- CE_A = E_C < E_B
- DE_A > E_B > E_C
Correct answer
B. E_A = E_C > E_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
