The angle between the dipole moment and electric field at any point on the equatorial plane is
- A \( 0^{\circ} \)
- B \( 90^{\circ} \)
- C \( 180^{\circ} \)
- D \( 45^{\circ} \)
Answer & Solution
Correct Answer
(C) \( 180^{\circ} \)
Step-by-step Solution
Detailed explanation
Dipole moment points in a direction from negative charge towards positive charge as shown in the figure. At equatorial plane, the electric field points in a direction just opposite to that of dipole moment. Hence the angle between dipole moment and electric field at any point on equatorial plane is \(180^{\circ}\).
