Homework Help: Newtons Law of Gravitation

  1. Mar 30, 2008 #1
    1. The problem statement, all variables and given/known data
    What is the ratio of the gravitationalpull of the sun on the moon to that of the earth on the moon?(Assume the distance of the moon from the suncan be approximated by the distance of the earth from the sun.)


    2. Relevant equations

    F[tex]_{g}[/tex] = (Gm[tex]_{1}[/tex]m[tex]_{2}[/tex])/r^{2}

    3. The attempt at a solution

    What i got from the question the surface to surface distance is the same and to calculate F_{g} so using the orbital distance of the earth from moon i found out theorbital disrance of sun to moon but my answer s totally different from the aI am to get


    Thanks for any help possible

    The question said to use the distance between the Sun and the Earth as the distance between the Sun and the Moon.
