A solid spherical non-conductor of radius 14. 5 cm has a uniform charge density of = 3. 50 µC/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 23. 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 = 23. 0 = _____________N/C
