The product of electric field intensity and area is the flux ΦE. Whereas E is an intensive quantity, ΦE is an extensive quantity. It dimensions are ML3T-2Q-1 and its SI units are N m2 C-1, although later on, after we have met the unit called the volt, we shall prefer to express ΦE in V m.The surface charge density (charge per unit of surface area) of the thin sheet is σ: The Gaussian surface through which we are going to calculate the flux of the electric field is represented in red. It is a cylinder perpendicular to the thin sheet. The vector dS is also represented for each side of the cylinder.The electric flux density R2 is derived from the radius and surface area of the surface area. This is where the flux passes from one unit area to another at a distance of r from the center of the charge. At some point, we will be able to demonstrate that this is electric flux density. This symbol is spelled in English with the letter D.The surface can be divided into small patches having area Δs. Then, the charge associated with the nth patch, located at rn, is. qn = ρs(rn) Δs. where ρs is the surface charge density (units of C/m 2) at rn. Substituting this expression into Equation 5.4.1, we obtain.

(d) How much charge is contained within the sphere r= 4?For that purpose, we need to cut the cylinder along its length, and we will find out that the area is equal to 2πrL. So, 2πRL times E is equal to the charge enclosed divided by E 0. The charge density λ is the total charge Q per length L, so the Q enclosed is equal to λL. So, 2πRLE is equal to λL divided by E 0. Whereas in the integral form we are lookin

Hence, units of electric flux are, in the MKS system, newtons per coulomb times meters squared, or N m 2 /C. (Electric flux density is the electric flux per unit area, and is a measure of strength of the normal component of the electric field averaged over the area of integration. Its units are N/C, the same as the electric field in MKS units.)Multiply the magnitude of your surface area vector by the magnitude of your electric field vector and the cosine of the angle between them. With the proper Gaussian surface, the electric field and surface area vectors will nearly always be parallel. 6. Do not forget to add the proper units for electric flux.
