A conductor lies along the z-axis at –1.5 ≤ z < 1.5 m and carries a fixed current of 10.0 A in –a z direction (see figure). For a field B r = 3.0 × 10 –4 e –0.2x y a ˆ T, find the power required to move the conductor at constant speed to x = 2.0 m, y = 0 m in 5 × 10 –3 s. Assume parallel motion along the x-axis - 2.0 1.5 z y I B –1.5 x
