A Speck Of Dust!

Classical Mechanics Level 4

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., $g=10 \text{ ms}^{-2}$ )
