    A point charge +Q is positioned at the center of the base of a square pyramid as shown. The flux through one of the four identical upper faces of the pyramid is

    A) \[\frac{Q}{16{{\varepsilon }_{0}}}\]

    B) \[\frac{Q}{4{{\varepsilon }_{0}}}\]

    C) \[\,\frac{Q}{8{{\varepsilon }_{0}}}\]      

    D) \[0\]

    Correct Answer: C

    Solution :

    [c] Flux going in pyramid\[=\frac{Q}{8{{\varepsilon }_{0}}}.\] Which is divided equally among all 4 faces. \[\therefore \]Flux through one face\[=\frac{Q}{8{{\varepsilon }_{0}}}\]
