Two very large sheets of plastic are facing each other with a distance 'd' between them. By rubbing them with wool and silk, the sheet on the left gets a uniform surface charge density n1=−n0 and the other sheet on the right gets n2=3n0, where n0 > 0. What is the magnitude and direction of the electric field in the region between the two sheets?

A) n0/𝜀0, left              B) n0/𝜀0, right               C) 2n0/𝜀0, left              D) 2n0/𝜀0, right
