The problem is generalised in the sense that more massive primary has been taken as an oblate spheroid. We have found the position of triangular equilibrium points. We have obtained variational equations of the problem. With the help of characteristic roots, we conclude that the triangular points are unstable. Robe's result may be verified from the generalised result.6 PagesDynamical Systems70F15text
