1. Suppose you land on a planet with 3 times the mass of Earth, but the same size. How would your weight on this planet compare to your Earth weight? 

2. Suppose you land on a planet with 10 times the radius of Earth, but the same mass. How would your weight on this planet compare to your Earth weight?

3. Suppose you landed on a planet with half the mass and half the radius of Earth. What would your relative weight be? (Hint: compare to the case given in the introduction with double the mass and radius)

4. Suppose you landed on a planet with 4 times the mass and twice the radius of Earth. What would your relative weight be?

5. The mass of the Moon is 0.012 Earth masses, and its radius is 0.27 Earth radii. What would your relative weight on the Moon be?
