imagine this scenario. you have two equally massive objects, exerting an equal amount of gravitational force (they are perfect spheres), and they are held apart a certain distance (how they are held apart is irrelevant). for simplicity, lets just say that their masses are about the same as that of earth, and that the distance between them is fairly small; say, a few miles or so, close enough so they would both have a strong gravitational pull. now here comes my question: if you placed a third object with a much smaller mass (although large enough to be affected by gravity... perhaps a 100kg sphere?) right at the midpoint between these two masses, what would happen to it? my first thought that was it would be torn in two and each half would go towards the closer mass... but how would any movement be able to happen if the net force is zero? maybe you guys can help me figure out what would happen to the middle object?
