Terminal Velocity

A lead sphere of mass ' $m$ ' falls in viscous liquid with terminal velocity $\mathrm{V}_0$ . Another lead sphere of mass ' 8 m ' but of same material will fall through the same liquid with terminal velocity

Show answer and solution

Answer: (c)

Same material: $m \propto r^3$ , so $8m \Rightarrow r' = 2r$ .
$v \propto r^2 \Rightarrow v' = 4V_0$
So the answer is (c) $4V_0$ .
