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 $\sigma 0$. The separation between any two consecutive sheets is 1m. The various regions between the sheets are denoted as $1,2,3,4$ and 5 . If $\sigma_0=9 \mu \mathrm{C} / \mathrm{m}^2$, then which of the following statements is/are correct: (Take permittivity of free space $\epsilon_0=9 \times 10^{-12} \mathrm{~F} / \mathrm{m}$ )
