Terminal Velocity

A tiny water droplet falls through the air at a uniform terminal speed of $1$ cm/s. If $27$ such identical droplets coalesce to form a single larger drop, what will be the new terminal velocity of the resulting drop, assuming the air remains the same?

Show answer and solution

Answer: (d)

$v \propto r^2$ and $R = 27^{1/3}r = 3r$ .
$v' = 3^2 \times 1 = 9$ cm/s
So the answer is (d) $9$ cm/s.
