the velocity of a small block of mass 0.3 gram and density 8 gram per CC and drop in a container filled with glycerine become constant after sometime. If the density of glycerine is 1.3g/cc, then the value of viscous force acting on a ball will be x*10^-4 N, the value of x is______.

Question

the velocity of a small ball of mass 0.3 g and density 8 g/cc 

and drop in a container filled with glycerine become constant after sometime. If the density of glycerine is 1.3g/cc, then the value of viscous force acting on a ball will be x*10^-4 N, the value of x is______.

Answer 1

F_v + F_B = mg (V = constant)
