(f) Describe from first principles how the relative positions of Lagrange Points L1, L2, and L3 can be found in a one-dimensional representation of the Sun-Earth system, by considering a spacecraft at those three locations. Use the following definitions for relevant terms: ms = mass of Sun me = mass of Earth re = radius of Earth's orbit r = displacement from Sun to spacecraft x = displacement from Earth to spacecraft The numerical values of these terms do not need to be derived
