13. (a) The charge on the surface of the sphere is the product of the surface charge density σ and the surface area of the sphere (which is 4 πr 2 ,where r is the radius). Thus, q =4 πr 2 σ =4 π µ 1 . 2m 2 2 ( 8 . 1 × 10 6 C / m 2 ) =3 . 66 × 10 5 C . (b) We choose a Gaussian surface in the form of a sphere, concentric with the conducting sphere and
