Q173 / 200 · MHT CET - Medical 2026 (22 April Shift 2) · Physics
Equipotential surfaces associated with an electric field that is increasing in magnitude along the positive Y-direction are
- Aplanes parallel to XY plane.
- Bplanes parallel to YZ-plane.
- Correct answerCplanes parallel to XZ-plane.
- Dplanes parallel to Y-direction.
Solution
The electric field is directed along the Y-axis.
Equipotential surfaces are always perpendicular to the direction of the electric field.
Since the electric field is along the Y-direction, the equipotential surfaces must be perpendicular to the Y-axis.
Planes perpendicular to the Y-axis are parallel to the XZ-plane.
The increasing magnitude of the electric field along the positive Y-direction implies that the spacing between consecutive equipotential surfaces decreases along this direction, but their orientation remains parallel to the XZ-plane.
Answer: planes parallel to XZ-plane.

Answer: planes parallel to XZ-plane.
Hence, the correct answer is option: 'C'.
