figure(a) shows three sheets that are large, parallel and uniformaly charged. Figure (b) gives the component of the net electric field along and x-axis through the sheets. The scale of the vertical axis is set by `E_(s)= 6.0 xx10^(5)N//C` what is the ratio of the charge density on sheet 3 to that on sheet 2?
