Three very large sheets are separated by equal distances of d = 16.9 cm as seen in the figure below.

Three very large sheets are separated by equal distances of d = 16.9 cm as seen in the figure below. The first and third sheets are very thin and nonconducting and have surface charge densities of σ1 = +5.02 uC/ m2 and σ2 = -5.02 uC/ m2 respectively. The middle sheet is conducting but has no net charge.

What is the electric field between the left and middle sheets (Use to the right as the positive direction)?
