How thick a layer would earth form as it wraps around the neutron star’s surface? assume that the layer formed by earth has the same average density as the neutron star. (hint: consider the mass of earth to be distributed in a spherical shell over the surface of the neutron star and then calculate the thickness of such a shell with the same mass as earth. the volume of a spherical shell is approximately its surface area times its thickness: vshell=4πr2×thickness. because the shell will be thin, you can assume that its radius is the radius of the neutron star.)
