The force is in Newton
The buoyant (upward) force exerted by water on a submerged object is given by the formula F= ?Vg, where ? is the density of water (1.0 x 103 kg/m3), V is the volume of the object in m3, and g is the acceleration because of gravity (9.80 m/s2). The force is in Newton. Rewrite the equation to find V in terms of F. Use this to find the volume of a submerged barrel if the buoyant force on it is 9200 N
