Two large parallel thin plates having uniform charge densities `+ sigma and - sigma` are kept in X-Z plane at a distance  d apart. Sketch an equipotential surface  due to electric  field between the plates. If a particle  of  mass m and charge  `-q` remains stationary between the plates, what is the magnitude and direction  of the filed ?
