Question

The velocity of a small ball of mass ‘m’ and density d1, when dropped in a container filled with glycerine, becomes constant after some time. If the density of glycerine is d2, then the viscous force acting on the ball, will be :

Select the correct option:

$m g\left(1-\frac{d_1}{d_2}\right)$

$\operatorname{mg}\left(1-\frac{d_2}{d_1}\right)$

$\operatorname{mg}\left(\frac{d_1}{d_2}-1\right)$

$\mathrm{mg}\left(\frac{\mathrm{d}_2}{\mathrm{~d}_1}-1\right)$

✓ Correct! Well done.
