I'm having trouble with this problem: Consider a thin spherical shell of radius 14.5 cm with a total charge of +38.9 microCloumbs distributed uniformly on its surface. (Take radially outward as the positive direction.) So I need to find the field at 35.6cm from the center of the charge distribution. Since this r is bigger than the shell R E= k_e * Q/ r^2 ; right? E = 8.99*10^9 * (38.9 * 10^-6)/(0.356)^2; right? I get 2759365.9260194. My answer is MN/C so I put 2.76 No dice. Did I miss something? I also tried 0.276, 27.6, 276, 2760, 27600, 276000, and 2760000 to be sure that the program wasn't just disregarding which units it wanted.
