Six infinitely large and thin non-conducting sheets are fixed in configurations I and II. As shown in the figure, the sheets carry uniform surface charge densities which are indicated in terms of σ₀. The separation between any two consecutive sheets is 1 μm. The various regions between the sheets are denoted as 1, 2, 3, 4 and 5. If σ₀ = 9 μC/m², then which of the following statements is/are correct: (Take permittivity of free space ε₀ = 9 × 10⁻¹² F/m)
