The figure below shows two parallel conducting rails, oriented vertically, connected to each other at the top by a wire with a
resistance R. A conducting metal rod is oriented horizontally and is in contact with the two vertical rails. The horizontal rod has a
length L = 50.0 cm and mass 35.0 g. The rod is released from rest at location A and begins to fall through a region of uniform
magnetic field indicated by the shaded area in the figure. When the rod reaches point B, there is an induced current of 1.85 A
flowing to the left in the rod, and the rod is moving downward with an acceleration of magnitude 7.85 m/s?.
What are the direction and magnitude of the magnetic field in the shaded region?
