Homework Statement
A solid metal sphere of radius 'a' is concentric with a hollow metal sphere of inner radius '2a'. The space between the spheres is filled with a dielectric material of relative permittivity 'ε' carrying a uniform static charge density 'ρ0'. The charge density is zero outside the spheres.
My question:
In the answers at the back of my book 'p0' is equated to the free charge density 'pf'. Shouldn't it be equated to charge density?
I know I'm getting hung up on the wording but it might show a large gap in my understanding of dielectrics.
Homework Equations
Charge density = free charge density + bound charge density
