Question:

Our galaxy can be considered to be a large disk of radius R and mass M of approximately uniform mass density.

(a) Consider a ring element of radius r and thickness d_r of such a disk. Find the gravitational potential energy of a 1-kg mass on the axis of this element a distance x from its center.

(b) Integrate your result for part (a) to find the total gravitational potential energy of a 1-kg mass at a distance x due to the disk.
