6.11 The loop shown in P6.11 moves away from a wire carrying a current I1 = 10 A at a constant velocity u = §7.5 (m/s). If R = 10 N and the direction of I2 is as defined in the figure, find I2 as a function of yo, the distance between the wire and the loop. Ignore the internal resistance of the loop. 10 cm I1 = 10 A 20 cm Уo

In the accompanying figure, the rails, connecting end pieces, and rod all have a resistance per unit length of 40/cm. The rod moves to the left at v = 3 m/s. If B = 0.65 T everywhere in the region, what is the current in the circuit (a) when a = 8 cm? (b) when a = 4.5 cm? Description of Image B Hint a. When a = 8 cm, a counterclockwise mA flows in the circuit. b. When a = = 4.5 cm, 5.48 o current of 9.75 4.0 cm X = 5.48 mA flows in the circuit. X = 9.75

1) A 5.50 m length of 1.9 mm -diameter wire carries a 780 mA current when 23.0 mV is applied to its ends. The drift velocity is 1.2×10−5 m/s Part D Determine the electric field inside the wire. Express your answer to two significant figures and include the appropriate units. Part E Determine the number n of free electrons per unit volume. Express your answer using two significant figures.
