MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A solid spherical non-conductor of radius 14.5 cm has a uniform charge density of p = 3.90 pC/m3. (a) Find the magnitude of the electric field at a distance of 9.30 cm from the center of the sphere. N/C (b) Find the magnitude of the electric field at a distance of 21.0 cm from the center of the sphere. N/C (c) Now consider a solid spherical conductor of same radius with the same total charge as the non-conducting sphere in part (a). Find the electric field at the two distances indicated in parts (a) and (b). Er = 9.30 = N/C Er = 21.0 = N/C Additional Materials Tutorial
