When the weight of the body is equal to the buoyant force.

(B) body floats on the surface of a liquid when the weight of the body is exactly balanced by the buoyant force (upthrust) exerted by the liquid.According to the law of floatation,for a body to float in equilibrium,the weight of the body must be equal to the weight of the liquid displaced by the submerged part of the body.Mathematically,$W_{body} = F_{buoyant}$.If $W_{body} > F_{buoyant}$,the body will sink.If $W_{body} < F_{buoyant}$,the body will rise to the surface and float partially submerged.
