The figure below shows two thin nonconducting plastic sheets, each with uniform charge densities, parallel to each other. (The sheets are very large and very close to each other, so at the locations stated below, you may approximate them as infinite.) Ⓡ The left sheet's charge per area is , while the right sheet's is - (where > 0). What is the magnitude and direction of the electric field at the locations specified below? (Use any variable or symbol stated above along with the following as necessary: £.) (a) to the left of the two sheets magnitude direction magnitude direction (b) in-between the two sheets direction (c) to the right of the two sheets magnitude magnitude direction -σ Now imagine both sheets have positive uniform surface charge densities. In parts (d)-(f) below, find the magnitude and direction of the electric field at the specified locations for this case.
