Screwed up the force equation in the last few steps. The denominator should be r^2 rather than r^3. Thanks so much for your help Fightfish.

Okay I got the answer for part (b) and I tried to do the same kind of operation for part (d) but The answer doesn't seem to work out. F_1 = \frac{G m_1 m_2}{(2r)^2} F_3 = \frac{G m_1 m_2}{(3r)^2} \frac{F_1}{F_3} = \frac{\frac{G m_1 m_2}{(2r)^2}}{\frac{G m_1 m_2}{(3r)^2}}...

Homework Statement Three satellites orbit a planet of radius R, as shown in the figure. Satellites S_1 and S_3 have mass m. Satellite S_2 has mass 2 m. Satellite S_1 orbits in 250 minutes and the force on S_1 is 10,000 N. See attached figure (knight_Figure_12_26.jpg). a. What is the...
