Mass M is distributed uniformly over a disk of radius a.

Find the gravitational force (magnitude and direction) between this disk-shaped mass and a particle with mass m located a distance x above the center of the disk (the figure ).(Hint: Divide the disk into infinitesimally thin concentric rings, use the expression F = GMmx / (r^2 + x^2)^3/2 for the gravitational force due to each ring of radius r, and integrate to find the total force.)
