Problem 1: The eight cases below show a moon orbiting a planet. The moons, planets, and orbits all have different masses and radii according to the diagrams. As you create the following rankings, you are strongly encouraged to write symbolic expressions for each quantity that you are ranking in order to make the best judgments in ranking. 4M om Om 0 4m 0 4m AR R R Case A Case B Case C Case D 0 4m 0 4m Om om Case E Case F Case G Case H (a) Rank the moons based on the net force acting on them from greatest to least. Explain your rankings below (perhaps using equations along with words). Put an equal sign between two equal forces. Greatest Net Force Least Net Force
