Electric FluxFor r<aAaRrFigure 4.17EWe select a spherical gaussian surface of radius r, concentric with thecharge sphere where r<a. The electric field E is perpendicular to thegaussian surface as shown in figure 4.17. Applying Gauss law we getqdA in∫ E r r. =ε οIt is important at this point to see that the charge inside the gaussian surfaceof volume V` is less than the total charge Q. To calculate the charge q in , weuse q in =ρV`, where V`=4/3πr 3 . Therefore,q in =ρV`=ρ(4/3πr 3 ) (4.11)2E ∫ A = E(4πr) =qinε ο4 3qinρ3πrρE = = = r(4.12)2 24πεοr 4πεοr 3εοQsince ρ =4 a 3π3Qr∴ E =34πε οa(for r<a) (4.13)Note that the electric field whenr<a is proportional to r, and whenr>a the electric field is proportionalto 1/r 2 .E 10 13 N/C1.20.80.41.0 2.0 3.0r 10 -10 mwww.hazemsakeek.com
