Two equal drops of water are falling through air with a steady volocity of `10 cm//s`. If the drops recombine to form a single drop what would be their terminal velocity ?

Explanation

To solve the problem of finding the terminal velocity of a single drop formed by the recombination of two equal drops, we can follow these steps:

### Step 1: Understand the relationship between terminal velocity and radius
The terminal velocity \( V_t \) of a drop is given by the formula:
\[ V_t \propto r^2 \]
where \( r \) is the radius of the drop. This means that the terminal velocity is proportional to the square of the radius.
