A sphere of radius R = 0.315 m and uniform charge density 151 nC/m lies at the center of a spherical, conducting shell of inner and outer radii 3.50R and 4.00R, respectively. The conducting shell carries a total charge of Q = -38.1 nC, Determine the magnitude E(r) of the electric field at the given radial distances from the center of the charge distribution. E (0.460R) = 824.1 N/C R E (3.80R) = = 0 N/C E (3.25 R) = 169.7 N/C E (5.10R) = Incorrect N/C 3.50R 4.00R
