Homework Statement
A sphere, which is hollow, has an inner radius (denoted x) and an outer radius (denoted y).
The sphere does not conduct.
It has a charge of 5 C distributed uniformly throughout it.
1) What is the charge density by volume in the body of the hollow sphere?
2) How much charge is enclosed in a gaussian sphere of radius x < r < y?
Homework Equations
(4/3)(pi)(r3) is the volume of a sphere with radius r.
The Attempt at a Solution
I know you divide the charge by the volume of the sphere. Since the sphere is hollow, can you assume that the 5 C of charge are distributed in the hollow part too, or only on the edge?
My instinct is to calculate the volume using radius y, but I'm not sure.
