A ring of radius 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 11.7 kg/m, while the portions of the ring in the second and fourth quadrants have a mass denisty of 8.5 kg/m. Find the z-component of the gravitational field due to the ring at a point P on the z-axis at a distance 6 m from the origin. Use G = 6.673e-11 N*m^2/kg^2 9z =
