Question

Equipotential surfaces associated with an electric dipole are:
Options
A spheres centered on the dipole
B planes perpendicular to the dipole moment
Correct Answer
C planes parallel to the dipole moment
D none of the above
Correct Answer

Option B is the correct answer.

Detailed Explanation

For a dipole (+q and -q), every point on the plane that cuts perpendicularly through the middle of the dipole axis is equally far from both charges. The +q contribution and the -q contribution cancel exactly there, giving V = 0 across that whole plane - a flat equipotential surface perpendicular to the dipole moment.

Hint

For a dipole (+q and -q), every point on the plane that cuts perpendicularly through the middle of the dipole axis is equally far from both charges.
