A 60 gg horizontal metal bar, 14-cmcm-long, is free to slide up and down between two tall, vertical metal rods that are 14 cmcm apart. A 6.0×10−2 TT magnetic field is directed perpendicular to the plane of the rods. The bar is raised to near the top of the rods, and a 1.0 ΩΩ resistor is connected across the two rods at the top. Then the bar is dropped. What is the terminal speed at which the bar falls? Assume the bar remains horizontal and in contact with the rods at all times.

A 60 gg horizontal metal bar, 14-cmcm-long, is free to slide up and down between two tall, vertical metal rods that are 14 cmcm apart. A 6.0×10−2 TT magnetic field is directed perpendicular to the plane of the rods. The bar is raised to near the top of the rods, and a 1.0 ΩΩ resistor is connected across the two rods at the top. Then the bar is dropped. What is the terminal speed at which the bar falls? Assume the bar remains horizontal and in contact with the rods at all times.
