Electromagnetic Field Theory
A long wire composed of a smooth round conductor runs above and parallel to the ground (assumed to be a large conducting plane). A high voltage exits between the conductor and the ground. The maximum electric stress occur at

 The ground surface.
 The upper surface of the conductor.
 Midway between the conductor and ground.
 The lower surface of the conductor.

Electromagnetic Field Theory
The statement which is not correct from the following:

 An electric flux line is an imaginary path or a line drawn in such a way, that its direction at any point is the direction of electric field at that point.
 For a uniform long charged line with l1 c/m the electric field intensity E is given as E = ρL/(π ε0.r).
 Gauss’s static that divergence of D = ρu.
 Gauss’s law states that total electric flux through any surface is equal to the total charge enclosed by surface.
