Small water droplets of radius $\displaystyle 0.01$ mm are formed in the upper atmosphere and falling with a terminal velocity of $\displaystyle 10 \mathrm{~cm} / \mathrm{s}$. Due to condensation, if $\displaystyle 8$ such droplets are coalesced and formed a larger drop, the new terminal velocity will be $\displaystyle \_\_\_\_$ cm/s.
