A small ball of mass m and density `rho` is dropped in a viscous liquid of density `sigma`. Ather some time the ball falls with a constant velocity. Calculate the viscous force acting on the ball.

The velocity of a small ball of mass M and density d when dropped in a container filled with glycerine becomes constant after sometime. If the density of glycerine is 'd/2' then the viscous force acting on the ball will be
