Law of Floatation

Law of floatation 1 p> of : Body sink completely 2 Pf= If : Body sin- KS on the surface (Just Sink) 3 If LPf : Body floats when a body floats only when volum weight of the body is equal to weight of fluid displaced And volume of fluid is equal to volume of immersed part of the body. N6 F6 = Wf If = Vimmersed part V : volumeuf boay V': volume of body immers- ecl. 6 P a = ciensity of fluid 6 = density of body
