Electromagnetic Field Theory
A metal sphere with 1 m radius and a surface charge density of 10 coulombs/m2 is enclosed in a cube of 10 m side. The total outward electric displacement normal to the surface of the cube is
Gauss’s law states that total electric flux through any surface is equal to the total charge enclosed by surface.
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).
