A conducting rod of mass m = 10 g, length L=20 cm and negligible resistance is lightly connected by two conducting rings to vertical metal rails as shown in Figure. The rails are connected to resistors R₁ =3.00 and R₂ = 6.00 to complete closedcircuits. A constant magnetic field, B = 4.0 T, is directed out of the page. = • Show the direction of the induced current in each of the resistors. • Calculate the terminal velocity of the falling bar. Use Faraday's EMF law in your derivation. Assume the bar reaches this speed quickly - before it hits the bottom resistor. Hint: first determine the net induced current through the bar.
