A conducting rod of length = 35.0 cm is free to slide on two parallel conducting bars as shown in the figure below. Two resistors R₁ = 2.00 and R₂ = 5.00 are connected across the ends of the bars to form a loop. A constant magnetic field B = 2.10 T is directed perpendicularly into the page. An external agent pulls the rod to the left with a constant speed of v = 7.65 m/s. Find the following.
