  • question_answer
     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)  None of these

    Correct Answer: C

    Solution :

     Flux going in pyramid \[=\frac{Q}{2{{\varepsilon }_{0}}}\] Which is divided equally among all 4 faces \[\therefore \] Flux through one face \[=\frac{Q}{8{{\varepsilon }_{0}}}\]
