Question: The acceleration due to gravity at the North Pole of Neptune is approximately 10.7 m/s2. Neptune has mass 1.0 X 16'6 kg and radius 25

The acceleration due to gravity at the North Pole of Neptune is approximately 10.7 m/s2. Neptune has mass 1.0 X 16'6 kg and radius 25 X 104 km and rotates once around its axis in about 16 h.
(a) What is the gravitational force on a 5.0-kg object at the north pole of Neptune?
(b) What is the apparent weight of this same object at Neptune's equator? (Note that Neptune's "surface" is gaseous, not solid, so it is impossible to stand on it.)
