# A Speck Of Dust!

Classical Mechanics Level 5

A speck of dust of negligible mass begins to fall under gravity through a region of space with saturated water vapor. The vapor condenses on it at a constant rate $$A$$ per second. Calculate acceleration of the drop in $$\text{ms}^{-2}$$.

Details And Assumptions

• Consider the drop to travel through uniform gravitational field ( i e., $$g=10 \text{ ms}^{-2}$$ )
