Law of Floatation…

Law of Floatation – When a body of density ρs and volume V is immersed in a liquid of density ρl,
(i) The body will float with fully immersed in the liquid, if the weight of the body is just balanced by upthrust. i.e. Vρsg < Viρlg
(ii) The solid body floats with a part of it in the fluid, if weight of the body is less than the upthrust. i.e. Vρsg < Viρlg
(iii) The body will sink, if weight of the body is greater than the upthrust. i.e. Vρsg > Viρlg
