    If 8 dipoles of charges of magnitude \[\pm \,e\] are placed inside the cube. The electric flux coming out of cube will be

    A)  \[16\,e/{{E}_{0}}\]                  

    B)  \[8\,e/{{E}_{0}}\]

    C)  \[75\,{}^\circ C\]                     

    D)  zero

    Correct Answer: D

    Solution :

    From Gauss theorem,\[{{\phi }_{E}}=\frac{{{q}_{in}}}{{{E}_{0}}}=\frac{+\,\,8\,e-8\,e}{{{E}_{0}}}\,\,=\,\,0\]
