Hi this is my first time posting on this forum. I have an question about Lagragian points. I was trying to find L2 lagrangian point, a point that lies on the line defined by the two large masses, beyond the smaller of the two. Here, the gravitational forces of the two large masses balance the centrifugal force on the smaller mass. Let's say the larger object has mass M and the smaller object has mass m, and the distance between the two objects is R and the distance from the smaller object to L2 is r, then how do you guys derive a formula to calculate r? I was given a hint that I need to use approximation method meaning R is exceedingly greater than r such that (r/R)^2 is equal to zero. Again, Unlike L1 which is located between the two objects, L2 lies behind the smaller object. At least if you can give me some hints, I would really appreciate. Thanks.
