8.8** Two masses m₁ and m₂ move in a plane and interact by a potential energy U(r) = kr². Write down their Lagrangian in terms of the CM and relative positions R and r, and find the equations of motion for the coordinates X, Y and x, y. Describe the motion and find the frequency of the relative motion.
