Question:medium
Eight identical spherical liquid drops, each falling with a terminal velocity $v$, coalesce to form a single large drop. The terminal velocity of the new large drop is:
Eight identical spherical liquid drops, each falling with a terminal velocity $v$, coalesce to form a single large drop. The terminal velocity of the new large drop is:
Show Hint
When identical drops combine:
\[
R = n^{1/3} r
\]
and since terminal velocity follows:
\[
v \propto r^2
\]
therefore:
\[
v' = n^{2/3} v
\]
