Two concentric, spherical shells of radii R and 3R carry uniform charges of -3Q and +7Q respectively as shown in the diagram below. What is the magnitude of the electric field exterior to both spheres at a radial distance of r where r > 3R? (See the diagram below.) +7Q -3Q O a. 8 QTE 0r2 O b. 3 QTE 0 r2 OC. Q2TE 0r2 Od. QTE 0r2 3R E(r) =?
