1. The problem statement, all variables and given/known data 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? 2. Relevant equations 3. 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.
