    Equipotential surfaces associated with an electric field which is increasing in magnitude along the x-direction are

    A) planes parallel to yz-plane

    B) planes parallel to xy-plane

    C) planes parallel to xz ?plane

    D)  coaxial cylinders of increasing radii around the x-axis

    Correct Answer: A

    Solution :

    [a] Equipotential surface is always perpendicular to the direction of electric field. As the field is along x-direction, equipotential surface must be parallel to yz-plane.
