Athin metallic spherical shell of radius 0.357 m has a total charge of 5.03 times 10^-6 c placed on it. at the center of the shell is placed a point charge of 4.15 times 10^-6 c. what is the electric field at a distance of 0.815 m from the center of the spherical shell? gauss's law states that the total electric flux contained in an enclosed area (in this case, a shell of radius 0.815m from the center of the point charge) is proportional to the total charge within the enclosed area. thus, the electric field at the point of interest is the sum of the electric field due to the point charge and the electric field of the distributed charge treated as a point charge located at the center of the spherical shell.
