Attem A sphere of radius R = 0.250 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. If the conducting shell carries a total charge of Q = 40.5 nC, find Macmillan Learning the magnitude of the electric field at the given radial - distances from the center of the charge distribution. T - -441173.9 0.310R: N/C Incorrect R -2.1 x10-17 3.95R: N/C 3.50R Incorrect 4.00R 1.10R: N/C Incorrect 5.30R: N/C
