The velocity of a small ball of mass M and density d, when dropped in a container filled with glycerin becomes constant after some time. If the density of glycerin is $\frac {d}{2}$, then the viscous force acting on the ball will be:

(1) $\frac {Mg}{2}$
(2) $Mg$
(3) $\frac {3}{2} Mg$
(4) $2Mg$ Continue reading The velocity of a small ball of mass M and density d …. →
