Homework Statement
Three uniform spheres are located at the corners of an equilateral triangle. each side of the triangle has a length of 1.2m. two of the spheres have a mass of 2.8kg each. the third sphere(mass unknown) is released from rest. considering only the gravitational forces that the spheres exert on each other, what is the magnitude of the initial acceleration of the third sphere?
Homework Equations
F=G(m1m2/r2)
The Attempt at a Solution
I oriented the triangle so the two spheres with a known mass are along the y-axis, therefore the x-component of the forces cancel via symmetry and we're left w/ the y-component which is (2Gm1m2sin60)/r2
Am i doing this right so far?
