Three infinitely long charged non-conducting sheets are placed as shown in the figure. The electric field at point ' $\mathrm{P}$ ' is ( $\sigma$ - charge density, $\epsilon_0$ - permittivity of free space)
  1. $\frac{2 \sigma}{\epsilon_0} \hat{\mathrm{k}}$
  2. $\frac{-3 \sigma}{\epsilon_0} \hat{\mathrm{k}}$
  3. $\frac{4 \sigma}{\epsilon_0} \hat{\mathrm{k}}$
  4. $\frac{-2 \sigma}{\epsilon_0} \hat{\mathrm{k}}$
