In the following Questions, a Gaussian cylinder with radius a andl is placed in various electric fields. The end caps are labeled A and C and the side surfaces is labeled B. In each case, base your answer about the net flux only on qualitative arguments about the magnitude of the flux through the end caps and side surfaces.
C. The Gaussian cylinder encloses opposite charges of equal magnitude. (The charges are on the axis of the cylinder and equidistant from the center.)

- In which of the following contexts can Gausss law not be readily applied to find the electric field? (a) near a long, uniformly charged wire (b) above a large, uniformly charged plane (c) inside a uniformly charged ball (d) outside a uniformly charged sphere (e) Gausss law can be readily applied to find the electric field in all these contexts.arrow_forwardA very long line of charge with a linear charge density, , is parallel to another very long line of charge with a linear charge density, 2. Both lines are parallel to the y-axis, and are the same distance r from the y-axis, where the first wire is to the left of the origin and the second is to the right. Use Gausss law and the principle of superposition to find an expression for the magnitude of the electric field at the origin.arrow_forwardConsider eight charges at the corners of a cube with side length a, and its axes parallel to the Cartesian coordinate axes, and its center at the origin, (0,0,0). a. If all eight charges have a value of q, evaluate the electric field along the x-axis, and explain its behavior as x goes to infinity. b. If the four charges where z= a/2 are +q and the other four are -q , evaluate the electric field along the x axis, and explain its behavior as x goes to infinity. c. Now consider having four +q and four -q charges, with each charge having its nearest neighbor have the opposite sign. Sketch this, evaluate the electric field along the x axis, and explain its behavior as x goes to inifinity.arrow_forward
- The figures show cross sections of three-dimensional closed surfaces. They have a flat top and bottom surface above and below the plane of the page. However, the electric field is everywhere parallel to the page, so there is no flux through the top or bottom surface. The electric field is uniform over each face of the surface.

- A net flux of 6.75×10^4N⋅m2/C passes inward through the surface of a sphere of radius 5.25 cm. a. What is the net charge, in coulombs, contained within the sphere? b. Which statement best describes the distribution of the charge inside the sphere? All of the charge is concentrated in a point charge. The flux indicates the net charge enclosed in the surface, but it yields no information about the distribution of the charge. The charge can be distributed in many different ways, but the distribution must be spherically symmetric. Both positive and negative charges are contained within the sphere, but most of the charges cancel yielding the net charge obtained in the previous step. The charge is uniformly distributed throughout the volume of the sphere. The charge is distributed over a thin spherical shell within the sphere.arrow_forwardFour concentric spheres S₁, S₂, S., and 5, are arranged as in the figure below and each charge in the figure has the same magnitude.
