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

  1. AE_A = E_B = E_C
  2. BE_A = E_C > E_B
  3. CE_A = E_C < E_B
  4. 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
