According to Newton's Law of Gravity, what is the ratio of the Sun's gravitational force on you to the Earth's gravitational force on you? Assume your mass is $m$, the mass of the Sun is $M_{\mathrm{sun}}$, the mass of the Earth is $M_{\mathrm{earth}}$, the distance from you to the Sun is $r_{\mathrm{sun}}$, and the distance from you to the Earth's center is $r_{\mathrm{earth}}$.
