    Three infinitely charged sheets are kept parallel to x-y plane having charge densities as shown. Then, the value of electric field at 'P is

    A) \[\left( 3+\frac{\pi }{2} \right)\]                

    B) \[\left( 3-\frac{\pi }{4} \right)\]

    C) \[y={{u}^{m}}\]               

    D) \[2{{x}^{4}}.y\frac{dy}{dx}+{{y}^{4}}=4{{x}^{6}}\]

    Correct Answer: C

    Solution :

    \[[O-N={{O}^{-}}]\]\[{{[N=O-O]}^{-}}\]
