Q1) In free space , a two infinite sheets of current, the first of k=2ax A/m at y= -3 and the second of k= -4ax A/m at y=5. 1) find the force on an area in the first sheet bounded by (0,-3,0), (2,- 3,0),(2,-3,3) and (0,-3,3) 2) if we put (between the two sheets) an infinite filament of current at y=0 and z=0, of 1A (in direction of positive x axis), find the force act on a piece of this filament bounded by (0,0,0) and (5,0,0).
