Homework Help: Gravitational Problem

  1. Oct 27, 2013 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations

    Gravitational problem. Fg = M1M2(G) / r^2

    G = 6.67e-11

    3. The attempt at a solution

    Furthest I got was setting up the equation Fg = (M0)(2M0)(G) / r^2

    I'm quite lost in this topic and would appreciate some help.

    I need to find both the magnitude and direction of the force on M.

    M0 is the mass of the object and x and y are the distances between M and the objects.

    There is a right angle between x and y.

    I would appreciate any help. Thanks!

    You determine the force on M due to M0, this acts to the LEFT.

    You determine the force on M due to M1, this acts downwards and to the left at some angle (you know the sides of a triangle there, so you can express the angle in terms of tan.)

    You then sum those two forces as vectors.
