Question

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 $L = 56.7$ cm and mass 30.3 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 2.45 A flowing to the right in the rod, and the rod is moving downward with an acceleration of magnitude 7.85 m/s$^2$. What are the direction and magnitude of the magnetic field in the shaded region? magnitude direction -Select-
