A conducting rod of length = 35.0 cm is free

A conducting rod of length = 35.0 cm is free to slide on two parallel conducting bars

Question:

A conducting rod of length ℓ = 35.0 cm is free to slide on two parallel conducting bars as shown in Figure P31.50. Two resistors R1 = 2.00 Ω and R2 = 5.00 Ω are connected across the ends of the bars to form a loop. A constant magnetic field B = 2.50 T is directed perpendicularly into the page. An external agent pulls the rod to the left with a constant speed of v = 8.00 m/s. Find
(a) The currents in both resistors,
(b) The total power delivered to the resistance of the circuit, and
(c) The magnitude of the applied force that is needed to move the rod with this constant velocity.
