360978 A ball of density \({\rho_{0}}\) falls from rest from a point \({P}\) onto the surface of a liquid of density \({\rho}\) in time \({T}\). It enters the liquid, stops, moves up, and returns to \({P}\) in a total time \({3 T}\). Neglect viscosity, surface tension and splashing. Find the ratio of \({\dfrac{\rho}{\rho_{0}}}\).
