A conductor lies along the z-axis at `-1.5 le z lt 1.5` m and carries a fixed current of 10.0 A in `-hata_(z)` direction (see figure). For a filed of `vecB = 3.0 xx 10^(-4) e^(-0.2x) hata_(y)` T, find the power required to move the conductor at constant speed to x=2.0 m, y=0 m in `5 xx 10^(-3)` s. speed to x=2.0 m, y=0 m in `5 xx 10^(-3)` s. Assume parallel motion along the x-axis.
