Question

The velocity of a small ball of mass m and density d1 when dropped in a container filled with glycerine becomes constants after sometime. What is the viscous force acting on the ball ? (density of glycerine is d2) (A) mg{1 – (d1 / d2)} (B) mg{1 – (d2 / d1)} (C) mg{d1 / (d1 – d2)} (D) mg{d2 / (d1 – d2)}

Answer 1

Answer:

all ball gain constant velocity....
