Electromagnetic Induction

Q-A one-turn rectangular loop oriented parallel to the x-y plane and having dimensions a = 2 cm, b = 11 cm moves with a constant velocity v = 20 m/s in the +x direction. An external agent (force) ensures that this velocity remains constant throughout the motion. The wire of which the loop is made has negligible resistance. A resistor R = 26 W (not shown) is connected in the upper side of the loop. At some point, the loop enters a region of constant, spatially uniform magnetic field B = 1.7 T pointing in to the page. The magnetic field covers a region of "thickness" d = 26 cm in the x-direction.Calculate the induced current in the loop for each configuration.
