Properties Of Solids And Liquids Question 252

Question: A marble of mass $x$ and diameter 2r is gently released in a tall cylinder containing honey. If the marble displaces mass y (< $x$ ) of the liquid, then the terminal velocity is proportional to

Options:

A) $x + y$

B) $x - y$

C) $\frac{x + y}{r}$

D) $\frac{x - y}{r}$

Show Answer

Answer:

Correct Answer: D

Solution:

[d] $v_{0} = \frac{2}{9} \frac{r^{2} (ρ - ρ ‘) g}{η}$

$N o w, x = \frac{4}{3} π r^{3} ρ o r ρ \propto \frac{x}{r^{3}}$

$S i m i l a r l y, ρ ‘ \propto \frac{y}{r^{3}}$

$∴ v_{0} \propto \frac{x - y}{r}$
