## 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)(r

^{3}) 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.
