Homework Statement
a 7.0 kg point mass and a 17 kg point mass are held in place 0.5m apart. A particle of mass (m) is released from a point between the two masses 0.2m from the 7.0kg mass along the line connecting the two fixed masses. Find the magnitude and direction of the acceleration of the particle.
Homework Equations
F_g= (Gm_1 m_2)/r^2
The Attempt at a Solution
The force between the two distant masses: (G*7kg*17kg) / (0.5m)2
I know that these two distant masses exert an equal and opposite gravitational force on one another, but I don't know how to relate this force to the force exerted on the point mass in between them.
