TERMINAL VELOCITY

In Milikan's oil drop experiment, a charged drop falls with terminal velocity V. If an electric field E is applied in vertically upward direction then it starts moving in upward direction with terminal velocity 2V. If magnitude of electric field is decreased to (E)/(2) , then terminal velocity will become

Two balls A and B have radii in the ratio 1 :4 . What will be the ratio of their terminal velocities in a liquid ?

At a given place two rain drops of volumes V and 8V are falling down with terminal velocities. Their terminal velocities are in the ratio

At a given place two rain drops of volumes V and 8V are falling down with terminal velocities.Their terminal velocities are in the ratio

The diameter of ball A is half of that of B. The ratio of their terminal velocities will be

The ratio of the terminal velocities of two drops of radii R and R//2 is

The radii of two drops are in the ratio of 3 : 2, their terminal velocities are in the ratio

Sixty four spherical rain drops of equal size are falling vertically through air with a terminal velocity 1.5ms^(-1) . If these drops coalesce to form a big spherical drop, then terminal velocity of big drop is:
