Find the resultant gravitational force exerted by the other two objects on the object at the origin. Magnitude = ?

    It looks good to me! I think maybe the \(5.55{\Tiny\rm E}-10\) could be rounded to match the significant figures of \(7.0\rm\ kg\), but it looks good.

    Then the answer would round up to \(2.1\times10^{-9}\rm\ N\).
