    A cubical box contains charge +Q at its centre. The total magnetic flux emerging from the box is :

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

    B)  \[\frac{Q}{6{{\varepsilon }_{0}}}\]

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

    D)         \[{{\varepsilon }_{0}}Q\]

    Correct Answer: A

    Solution :

    According to Gausss theorem, total electric flux \[\phi =\frac{Q}{{{\varepsilon }_{0}}}\]
