Figure below shows three imaginary surfaces coaxial with an isolated infinitely long line of charge with uniform linear charge density ? C/m: i. A closed cylinder of length L ii. A closed cube box with side L ii. A two dimensional square sheet with side L. the plane of the sheet is perpendicular to the line of charge. Choose all the above surfaces through which the net electric flux is ?_s = ?L / ?_0

Step 1
Given that the linear charge density is λ and the length of the cylinder is L, the charge passing through the cylinder is Q = λL. The flux through the cylinder surface is given by Φ = Q/ε₀ = (λL)/ε₀. Show more…

A uniform linear charge density of 30 nC/m is distributed along the entire x-axis. Consider a spherical (radius = 5.0 cm) surface centered on the origin. Determine the electric flux ( in units of N · m²/C) through this surface. use ε₀ = 8.8542×10⁻¹² F · m⁻¹.

Shown in the figure below are three concentric spherical Gaussian surfaces A, B, and C with a positive point charge +Q at their center. A second point charge with a negative charge -Q is enclosed only by surface C. Which is the correct statement about the magnitude of the electric flux Φ through the three surfaces? A) ΦA > ΦB > ΦC B) ΦA > ΦC > ΦB C) ΦB > ΦA > ΦC D) ΦA = ΦB = ΦC

(III) Uniform plane of charge. Charge is distributed uniformly over a large square plane of side $\ell$ , as shown in Fig. $68 .$ The charge per unit area $\left( \mathrm { C } / \mathrm { m } ^ { 2 } \right)$ is $\sigma .$ Determine the electric field at a point $\mathrm { P }$ a distance $z$ above the center of the plane, in the limit $\ell \rightarrow \infty .$ [Hint: Divide the plane into long narrow strips of width $d y ,$ and use the result of Example 11 of "Electric Charge and Electric Field"; then sum the fields due to each strip to get the total field at P.]
