Question: The acceleration g due to gravity, at a distance r from the center of a planet of mass m, is given by
g = Gm/r2
where G is the universal gravitational constant.
(a) Find ∂g/∂m and ∂g/∂r.
(b) Interpret each of the partial derivatives you found in part (a) as the slope of a graph in the plane and sketch the graph.
