A ball of mass

m

and radius

r

is gently released in a viscous liquid. The mass of the liquid displaced by it is

{m}^{\prime}

, such that

m > m^{\prime}

. The terminal velocity is proportional to

View answer and explanation

Correct option: A

\frac{m-m^{\prime}}{r}

Option A (

\frac{m-m^{\prime}}{r}

) is correct because the terminal velocity is proportional to the difference between the mass of the ball and the mass of the liquid displaced, divided by the radius.
