I just have a little question about Gauss' Law (differential form).

If divE = p/e0 where p is the charge density and e0 is permittivity of free space.

But if we had a sphere with a total net charge of Q, then outside the sphere, the field is E=k/r^2 I think.

Then at any r outside the sphere, divE evaluates to a non-zero value; but outside the sphere, p is zero at any r. So how does Gauss match up?

Thanks

2. Relevant equations

divE=p/e0
