Expert Answer
gravitational acceleraion gp of a planet is given by,
gp = ( G Mp / Rp2 )
where Mp is mass of planet and Rp is radius assuming the planet is spherical shape.
If mass is constant, then gravitational acceleration is inversely proportional to square of radius of planet.
Graph is shown below
