Question

The velocity of a small ball of mass m and density d when dropped in a container failed with listening become constant after sometime of density of glycerine is due to the viscous force acting on the ball is

Answer 1

Answer:

Since the ball attains equilibrium when the velocity becomes constant.

The effective force of the liquid must balance the viscous force

Effective force =V(d1−d2)g

But v=Md1

∴ effective viscous force =Md1(d1−d2)g

=Mg(1−d2d1)

Hence is the correct answer.
