Problem

Which expression gives the magnitude of the buoyant force acting on a completely submerged object of volume

V

in a fluid of density

\rho

, where

g

is the magnitude of the local gravitational acceleration? a)

F_b = 2\rho V g

F_b = \dfrac{1}{2}\rho V g

F_b = \rho V g

F_b = \rho_{\text{object}} V g
