c. Engineering Application: Electric Field for an Insulating Sphere of Charge Use filename: efield.cpp In Semiconductor Physics you will learn that Gauss' Law requires that an electric field exists whenever there is net electric charge in a region of space or in a material such as a perfect insulator. Figure 1 shows the arrangement for an insulating sphere that contains a total charge, Q coulombs, that is uniformly distributed within the sphere. E Figure 1 - Electric Field for Charged Insulating Sphere The magnitude of the electric field (N/C) at any radial distance from the center of the sphere is given by: E(r) = keQ· r< a a3' keQ r2 r > a Some requirements and recommendations for your program include: • Hardcode the following parameters as constant global variables of type double &: o Q = 10-9 C(oulomb) o ke = 9x10° (N – m²)/C² o rmin = e o rmax = 100 • In main(), set up a loop that spans all values of r in the range [rmin 100m] in increments of 1m. For each loop iteration, make a Om, rmax call to the function Efield(.) and pass in a specific radial location. The function prototype is given by %3D
