Review

To be specific, suppose an object displaces a volume $V_{\mathrm{displaced}}$ of fluid. If the fluid has density $\rho_{\mathrm{fluid}}$ , the fluid that the object displaces has mass $m_{\mathrm{fluid}} = \rho_{\mathrm{fluid}}V_{\mathrm{displaced}}$ and weight $m_{\mathrm{fluid}}g = \rho_{\mathrm{fluid}}V_{\mathrm{displaced}}g$ . Hence the magnitude $F_{\mathrm{b}}$ of the buoyant force that acts on the object is
