## Homework Statement

If the gravitational field vector g inside a sphere is independent of the

distance from the center of the sphere r, how does the density ρ(r) of the

sphere vary as a function of r?

## Homework Equations

gauss' law for gravity: integrate g*da=4*pi*G integrate ρ(r) dv

## The Attempt at a Solution

So far i have g=contant= (a/r^2) integrate 0 to r r^2 dr I am not sure what to do next.
