    1. The problem statement, all variables and given/known data
    What is the magnitude of the gravitational force on object #1 as a result of object #2? Distance A = 0.383 m and distance B = 0.271 m.
    the diagram for the problem is here:

    2. Relevant equations

    Fg= Gm1m2/r^2

    3. The attempt at a solution
    I tried simply plugging in the masses and using the distance for the radius.
    Fg= (6.67E+-11)(10)(10)/(.383)^2
    I don't know if object #2 is impacted by the gravitational force of object #3...I don't know how to incorporate that

    I would say that you've answered the question correctly, namely "What is the magnitude of the gravitational force on object #1 as a result of object #2?" You found [itex] \rm ||{\bf F}_{21}|| = \frac{Gm_1m_2}{r_{12}^2} [/itex] .

    Perhaps you should try to find the net force on object #1 now.
