Law of Floatation #8211; When a body of density ρ<sub>s</sub> and volume V is immersed in a liquid of density ρ<sub>l</sub>, (i) The body will float with fully immersed in the liquid, if the weight of the body is just balanced by upthrust. i.e. Vρ<sub>s</sub>g lt; V<sub>i</sub>ρ<sub>l</sub>g (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. Vρ<sub>s</sub>g lt; V<sub>i</sub>ρ<sub>l</sub>g (iii) The body will sink, if weight of the body is greater than the upthrust. i.e. Vρ<sub>s</sub>g gt; V<sub>i</sub>ρ<sub>l</sub>g
