Does the air exert buoyant force on all objects in air or only on objects such as balloons that re very light for their size?


Expert Answer

Step 1

The buoyant force is the product of the pressure difference between bottom to top surface of the object multiplied by the cross-sectional area.

Step 2

Now, there is always a pressure difference and area for any shape size objects. Therefore, there will always be a buoyant force...
