Expert Answer
We know that, the terminal velocity is given as
It is clear that the factor (ρ - σ), and hence, v will be negative.
Now, since 
, it follows that air bubbles rise slower than the bigger ones through a liquid.
, it follows that air bubbles rise slower than the bigger ones through a liquid.
