1. The mass of a robot is 5370 kg. This robot weighs 3520 N more on planet A than it does on planet B. Both planets have the same radius of 1.33 x 10^7 m. What is the difference MA - MB in the masses of these planets?

3. I was wondering what to do with the 3520 N. Do I find a ratio of weight between the planets and then multiply the original weight by that ratio? Do I need to use (G*mass/radius^2)? I'd appreciate some pointers or hints. I don't need the solution, just help with setting up the equation and understanding what I am looking for.
