A uniform solid sphere of mass \(M\) and radius \(R\) has a thin uniform ring of mass \(\dfrac{5M}{3}\) and radius \(\dfrac{4R}{3}\) around it. The two objects have a common centre \(O,\) and the axis of the ring \((PP')\) lies along a diameter of the sphere. Physical quantities associated with this system are mentioned in Column-I and their values in Column-II, but in a different order. Match them. Gravitational field is measured in units of \((GM/R^2),\) potential in units of \(\left(-\dfrac{GM}{R}\right)\) while potential energy is in units of \((-GM^2/R)\)
