An infinite conducting sheet lies in the xy plane. It has a width of 4.5 cm and a current density of 5200 A/m^2 in the negative direction. An election (m=9.11X10^-31 kg and q=-1.6X10^-19 moves parrallel to the sheet at a velocity of 2.5X10^6 m/s int he positive y direction and with an intial z-position of 4.0 cm.
