Terminal Velocity

Why terminals velocity so named?

(A): A bar magnet is dropped into a long vertical copper tube. Even taking air resistance as negligible, the magnet attains a constant terminal velocity. If the tube is heated, the terminal velocity gets increased. (R) : The terminal velocity depends on eddy current produced in bar magnet.

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
