A conducting rod of length = 65.0 cm is free to slide on two parallel conducting bars as shown in the figure below. Two resistors R1 = 6.00 Q and R2 = 9.00 Q are connected across the ends of the bars to form a loop. A constant magnetic field B = 10.0 T is directed perpendicularly into the page. An external agent pulls the rod to the left with a constant speed of v = 4.00 m/s. a) What is the magnitude and direction (positive terminal upward or positive terminal downward) of the emf induced in the moving rod? Think about which direction current will flow on the rod and remember current flows out of the positive end of a battery. b) Calculate the magnitude and direction (upward or downward) of the induced currents through each of two the resistors. c) Calculate the total power delivered to the resistors in the circuit. d) What is the magnitude of the external force required to keep the bar moving to the left at the constant speed of 4.00 m/s?
