The statement which is not correct from the following:

For a uniform long charged line with l1 c/m the electric field intensity E is given as E = ρL/(π ε0.r).

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.

Gauss’s law states that total electric flux through any surface is equal to the total charge enclosed by surface.

Gauss’s static that divergence of D = ρu.
