A sphere of radius R = 0.255 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 O = 90.5 nC, Determine the magnitude E(r) of the electric field at the given radial distances r from the center of the charge distribution. E(0.460R) = 667.1 N/C EBYR) = 0 N/C E(335R)= 1293 N/C E(5.90R) = N/C =" electric field at the given radial distances from the center of the charge distribution. Here ) - " v . . . 1(- = You can find the left hand side by multiplying we are using Gauss's Law, p ,,; = the magntude fo the electric field by the surface area of a sphere A l7r?. You can find the charge enclosed based on the charge distribution that is described in the problem. Inside the uniformly distributed charge in the center, the enclosed charge is Qone = P (':im"{_). [n the gap between the sphere and the shell, the enclosed charge is Edon p (_:%Tf:'i}:i). Inside the conducting shell, we know that the electric field is zero. And outside of the shell, vou will need to add the total enclosed charge from both the sphere and the shell
