How do you find the exact buoyant force of air?
B = pgV
where p = density of air (1.29kg/m3)
g = 9.81 m/s2
V = volume displaced
The problem is, you can't measure Volume directly. You have to do it experimentally by weighing a mass in air and then in water.
I can find the volume of the object in the air, only in water.
