15- The metal bar shown in the figure can move without friction on two rails with a distance of d = 4 m. The uniformly distributed magnetic field between the rails is B = 2 T and the rails are connected to each other by three resistors R1, R2 and R3 shown in the figure. The bar is pulled to the right with a constant velocity v. Since the magnitudes given in the figure are B = 2 T, v= 3 m/s, L = 6 m, d = 4 m, R1 = 1 ohm, R2 = 3 ohm, and R3 = 5 ohm, we can determine the magnitude and direction of the current passing through R3. find it.
