A solid has a volume of 8 cm³.When weighed on a spring scale calibrated in grams, the scale indicates 20 g.What does the scale indicate if the object is weighed while immersed in a liquid of density 2 g/cm³? A)4 g B)10 g C)12 g D)16 g E)zero, since the object will float

Question

Quizplus · Accepted Answer

The buoyant force on the object is equal to the weight of the liquid displaced by the object. The volume of the liquid displaced is equal to the volume of the object, which is 8 cm³. The density of the liquid is 2 g/cm³, so the weight of the liquid displaced is 8 cm³ x 2 g/cm³ = 16 g. The scale will indicate the weight of the object minus the buoyant force, which is 20 g - 16 g = 4 g.
