Theres a series of circles inside eachother. A central metal ball, two spherical metal shells, and three spherical Gaussian surfaces of radii R, 2R, 3R, all with the same center. The uniform charges on the three objects are: ball, Q; ssmaller shell, 3Q; Larger shell, 5Q. Rank the Gaussian surfaces according to the magnitude of the electric field at any point on the surface, greatest first. The image is attached.I don't get it because The electric field outside a spherical shell of charge with raidus R and total charge q is directed radially and has a mag of: E = 1/[4piEo] (q/r^2); So I ignored the 1/[4piEo] because they all will have that, the only difference is the charge and radius. So.... I ended up getting Q/R^2; 3Q/4R^2; 5Q/9R^2; How can these be equal?
