Q:(adsbygoogle = window.adsbygoogle || []).push({});

A mass of 5.000 kg is sitting on the Earth's surface directly under the sun during a solar eclipse. The sun exerts a gravitational force with magnitude Fs on the mass. The moon's gravitational force on the mass has magnitude Fm. Calculate the ratio Fs / Fm.

This problem is really frustrating me. For the object, wouldnt Fm be mg = 5*9.8?

Then wouldnt the Fs be (mass of the sun)(mass of earth)/R^2 ?

So wouldnt it be the Fs divided by Fm? Please help!?!?!
