3) When the rod is dragged to the right (sliding on the two metal rails), you find a tiny 1e-4 [A] current through the 25 [2] resistor. The magnetic field is 2 [T], into the page. How fast is the rod moving, in [m/s], at the moment shown? The metal rails are 10 [cm] apart on the left, and 15 [cm] across on the right. If you care (maybe you don't), the rod is at a 90° angle to the rails and that angle remains fixed as it slides along them. & Assuming whatever is moving the rod continues to move it at the same speed, what will happen to the current in the resistor when the rod starts sliding along the widely separated rails on the right? A qualitative answer is fine, but you can produce a number for this fairly easily as well.
