Thanks for your time. So if asked to find the charge when r>R, is the charge simply zero or do we consider the boundary conditions r=R? Thanks.

Homework Statement In a sphere of radius R, the charge density varies as \rho(r) = BrN. There is no charge outside the sphere. B and N are constants. a.) Find the charge enclosed in a sphere of radius r<R.Homework Equations \rho=dq/dvThe Attempt at a Solution I integrated \rho(r)(4\pir2dr)...
