I thought I did this problem correctly but when I submit my answer it says other wise.
Here is the problem: The mass of a robot is 5440kg. This robot weighs 3610N more on planet A than it does on planet B. Both planets have the same radius of [tex]1.33 * 10^7m[/tex]. What is the difference [tex]M_{A} - M_{B}[/tex] in the masses of these planets?
And I my answer must be in kg.
So I know to use:
[tex]W = G \frac{M_{E}m}{r^2}[/tex]
My answer for the mass on planet B was 12272.1 and for planet A was 13103.1. But when subtracting A - B my answer is wrong.
What am I doing wrong?
Thanks in advance for any help provided.
