Subject: Ideal Conductors and Capacitors

A conducting sphere of radius a, at potential V0, is surrounded by a thin concentric spherical 
shell of radius b, over which there is a surface charge given by σ(θ) = k cos θ, where k is 
a constant.
a. Show that the electric potential everywhere can be written as (look at picture)

b. Use the result from (a) to determine the induced surface charge density 
and the total charge of the system. At what location(s) is the charge density 
maximized or minimized?
