An object of mass 50 g just floats in a liquid of density 2.5 g/ml. when the object is placed in a liquid of density 2.0 g/ml, it sinks to the bottom of the container. what is the force that the object exerts on the bottom of the container? the solids density is [g = 10 m/s2 = 10 n/kg] can someone please write step by step, i would appreciate
