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
