Falling bar A conducting rod with a mass m and a length L can slide with no friction down a pair of vertical conducting rails, as shown in the figure below. The rails are joined at the bottom by a lightbulb of resistance R. The rails have stops near the bottom to prevent the rod from smashing the bulb. Thereis a uniform magnetic field of magnitude B directed out of the page. When the rod is released from rest, the force of gravity causes the rod to accelerate down the rails, but the rod eventually reaches a terminal velocity (that is, it falls at constant speed).

SHOW MORE a The current is always directed clockwise around the loop while the rod is falling. b The current is always directed counterclockwise around the loop while the rod is falling. C There is no current once the rod reaches its terminal velocity. d There is a constant (non-zero) current once the rod reaches its terminal velocity. e The faster the rod moves the brighter the light bulb is. The light bulb is brightest at the beginning and then gradually the bulb gets dimmer as the rod gets closer to its terminal velocity.@ Part (b) o Homework Unanswered Due Mar 19th, 12:15 PM Which graph best represents the shape of the graph of the magnitude of the induced current passing through the light bulb as a function of time while the rod is falling? .
