gnment NEXT FULL SCREEN PRINTER VERSION BACK Chapter 23, Problem 049 Your answer is partially correct. Try again. In the figure a solid sphere of radius a 3.40 cm is concentric with a spherical conducting shell of inner radius b-2.00a and outer radius c 2.40a. The sphere has a net uniform charge qí·+4.27 rc; the shell has a net charge q2--qi what is the magnitude of the electric field at radial distances (a) r-0 cm, (b) r-a/2.00, (c) r a, (d) r-1.50a, (e) r - 2.30a, and (f) 3.50a? What is the net charge on the (9) inner and (h) outer surface of the shell?

Explanation / Answer

looks like you have got the concept right. in number (g) as they have asked about the net charge on the inner surface, taking the gaussian just outside the inner surface( between b and c) one can conclude the net charge inside the Gaussian should be zero as there that is only possible if the inner charge on shell is -4.27 C.

Ans: it should be - 4.27 C just add the negative sign.
