Three non-conducting infinite planar sheets are parallel to the y-z plane. Each sheet has an unifomi surface charge density. The first sheet, with a negative surface charge density `sigma,` passes through the x-axis at x = Im. The second sheet has an unknown surface charge density and passes through the x- axis at x = `2`m. The third sheet has a negative surface charge density-`3`cr and passes through the x-axis atx = `4`m. The net electric field due to the sheets is zero at x = `1.5`m. Which of the following is/are correct :

Options

A. The surface charge density on the second sheet is `+2sigma`
B. The electric field at x=-`2` m is `(sigma)/(epsi)hati`
C. The electric field atx = 3m is `(sigma)/(epsi)hati`
D. The electric fieldatx =`6`m is `(-sigma)/(epsi)hati`
