Two infinite-plane non-conducting, thin sheets of uniform surface charge p1 = 12.30 uC/m2 and p2 = -3.30 uC/m2) are parallel to each other and d = 0.615 m apart. What is the electric field between the sheets? (Note: the field is positive if it is parallel to the vector x). Hi, I've tried this problem through the equation σ/2ε of sheet 1 + σ/2ε of sheet 2= E but that didnt seem to work. I also thought that maybe all the electric field lines were concentrated in the area between the two sheets since opposite charges attract. So i multiplied by two and that didnt work. Anyone got a clue to this problem?
