W.1.(1 pts) Shown in the figure is the gravitational accelerations ag as a function of the radial distance r from the center of the planet, for four planets. R1, R2, R3, and Ra are the radii of the respective planets and each plot starts from the surface of the planet. Plots 1 and 2 coincide for r2 R2: plots 3 and 4 coincide for r2 R. a) Rank the four planets according to mass, greatest first. Explain your reasoning 19 R4 R b) Rank the four planets according to mass per unit volume (density), greatest first. Explain your reasoning.
