A magnet is dropped down an infinitely long vertical copper tube

(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.

A bar magnet is made to fall through a long vertica! copper tube. The speed (V) of the magnet as a function of time (t) is best represented by

A: When a bar magnet is dropped into a vertical long hollow metallic tube, the magnet ultimately moves with zera acceleration. R: The magnet falling into metallic tube causes the eddy currents in the metal tube, so the motion of the magnet is damped.
