A tiny sphere of mass m and density x is dropped in a jar of glycerine of density y. When the sphere aquires terminal velocity, the magnitude of the viscous force acting on it is :

Statement -1 : A tiny shere of mass m and density rho is dropped in a tall jar of glycerine of density rho_(0) . When the sphere acquires terminal velocity v, the magnitude of viscous force is mg(1 - rho_(0)//rho) . Statement -2 : Viscous force on the body falling in a medium is F =6 pi eta r v , where eta is the coeff. of viscosity of medium and r is the radius of body

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
