The velocity of a small ball of mass ' $\displaystyle m$ ' and density $\displaystyle d_1$, when dropped in a container filled with glycerine, becomes constant after some time. If the density of glycerine is $\displaystyle \mathrm{d}_2$, then the viscous force acting on the ball, will be :
Official answer
(2)
$\displaystyle \mathrm{mg}\left(1-\frac{\mathrm{d}_2}{\mathrm{~d}_1}\right)$
