A Rod (Length = 10 Cm) Moves on Two Horizontal

question 1

Multiple Choice

A rod (length = 10 cm) moves on two horizontal frictionless conducting rails, as shown. The magnetic field in the region is directed perpendicularly to the plane of the rails and is uniform and constant. If a constant force of 0.60 N moves the bar at a constant velocity of 2.0 m/s, what is the current through the 12-Ω load resistor?

• A) 0.32 A
• B) 0.34 A
• C) 0.37 A
• D) 0.39 A
• E) 0.43 A
