Homework Statement
Given that the force of gravitation between Planet A (the one in the left side of the drawing), Fa=3000/da2 and the force of gravitation between Planet B and the rocket, Fb= 6000/ db2. Assuming that the three bodies involved is in stationary. What are the distances (ranges) from Planet A where the gravitational force is above 0.001 Newtons?
Homework Equations
The Attempt at a Solution
First, I solved if the Fa>0.001,
Fa=3000/da2
0.001<3000/da2
1732.054< da2
Therefore: 0 < da2 < 1732.054
Then I calculated if Fb>0.001
0.001<6000/db2
2442.75<db2
I subtracted the 2442.75 km from 6 000 000 km because the question asks what distances from planet A where the gravitational force is above 0.001 N.
5997557.25<da
0<da<5997557.25
Not sure if my answer was correct though, I'm still concerned with the middle body which is the rocket.
