Question

For an electric dipole (+q, −q), the equipotential surfaces are best described as:

Options

• Complex closed curves — bulged near the charges, pinched at the midpoint

• Concentric spheres centred at the midpoint between the charges

• Parallel planes perpendicular to the dipole axis

• Co-axial cylinders around the dipole axis

Answer 1

For an electric dipole (+q, −q), the equipotential surfaces form complex closed curves that are bulged near the charges and pinched at the midpoint. The corresponding field lines are curved lines running from +q to −q.
