Gravitational field from ring with two different mass densities A ring of radius 5.5 m lies in the x-y plane, centered on the origin. The portions of the ring in the first and third quadrants have a mass density of 2.8 kg/m, while the portions of the ring in the second and forth quadrants have a mass density of 6.5 kg/m. Find the z component of the gravitational field due to the ring at a point P on the z axis a distance 6 meters from the origin. Use G = 6.673E-11 N m2/kg2.
