    Finding the mass of two planets

    ok... I still don't get what I am supposed to do. Sorry. I get that weight is going to be calculated at the surface of the planets so d=1.33x10^7. I got the equation F=6.67x10^-11(5720m1/((1.33x10^7)^2)). I really just don't get what I am supposed to do after this.

    Finding the mass of two planets

I really don't even know where to start so I was hoping that you guys could help me. The problem is. The mass of a robot is 5720 kg. This robot weighs 3720 N more...
