Two infinite non-conducting sheets of charge are parallel to each other, with sheet A in the x = -2.5 m plane and sheet B in the x = +2.5 m plane. The electric field in the region x < -25 m, when each sheet has a uniform surface charge density equal to +30C/m :0 OD.3.4 x 105 NC 00:3.4 x 10% NIC Od -6.3 X 10 N/C O None of the above
