Three large parallel insulating sheets have surface charge densities s1 = –30 pC/m2,
s2 = +20 pC/m2, and s3 = +20 pC/m2. Adjacent sheets are a distance of 0.300 m from each other. Calculate the net electric field (magnitude and direction) due to all three sheets at points P, R, S, and T located midway between adjacent pairs.
