Viscosity & Stokes' Law

The velocity of a small ball of mass $M$ and density $d$ when dropped in a container filled with glycerine becomes constant after some time. If density of glycerine is $\frac{d}{2}$ then the viscous force acting on the ball will be ( $g$ =acceleration due to gravity)

Show answer and solution

Answer: (d)

At constant velocity: $F_v = Mg - B$ .
$B = V\frac{d}{2}g = \frac{Mg}{2}$ since $M = Vd$ .
$F_v = Mg - \frac{Mg}{2} = \frac{Mg}{2}$
So the answer is (d) $\frac{Mg}{2}$ .
