Let's model a planetary ring as having mass Mng = 2.30 x 1020 kg and radius R = 100,000 km. A body of mass m = 1,000 kg is placed at a point A on the axis of the ring, 2.00 x 108 m from the center of the ring (figure). When the object is released, the attraction of the ring makes the object move along the axis toward the center of the ring (point B).

Let's model a planetary ring as having mass Mng = 2.30 x 1020 kg and radius R = 100,000 km. A body of mass m = 1,000 kg is placed at a point A on the axis of the ring, 2.00 x 108 m from the center of the ring (figure). When the object is released, the attraction of the ring makes the object move along the axis toward the center of the ring (point B). (a) Calculate the gravitational potential energy (in J) of the object-ring system when the object is at A. (b) Calculate the gravitational potential energy (in J) of the system when the object is at B. (c) Calculate the speed (in m/s) of the object as it passes through B. m/s NASA
