1. Homework Statement
One dimension. In Fig. 1333, two point particles are fixed on an x axis separated by distance d. Particle A has mass mA and particle B has mass 7.00 mA. A third particle C, of mass 75.0 mA, is to be placed on the x axis and near particles A and B. In terms of distance d, at what x coordinate should C be placed so that the net gravitational force on particle A from particles B and C is zero?
2. Homework Equations
F=sqrt((GMm)/r^2) Where G=6.67E11
3. The Attempt at a Solution
I know that M=75 and m=7. Multiplying that by 6.67E11 I got 3.5E8/r^2. If i set that equal to 0, then I the r to disappear
