Question

we'll work througil uhe caitul 3. In this problem, of the electric field near the surface of a large, flat metal conductor. In the image at right, the square represents a section of the conductor's surface. The region above the surface is empty space, and below the surface is solid conducting metal. There is a uniform positive surface charge density +σ on the surface of the conductor. R I What is the electric field inside the conductor? Explain your reasoning. a) By symmetry, what is the direction of the electric field in the region just above the conductor? On the diagram at right, sketch the electric field in the region above the conductor. b) con or idd node To calculate the electric field strength, picture a Gaussian cylinder of length L and radius R, as shown in the diagram above. Find an expression for the electric cha the cylinder in terms of the constants given. c) eleceris hae d) Based on your expression, what is the total flux through the Gaussian cylinder? Is the flux through any of the sides of the cylinder zero? If so, which sides have zero flux, and why? e) arnlel and hue gome die f Based on your answers to the questions above, apply Gauss' law to find an expression for the electric field above the surface of the conductor.
