    In air the value of the total electric flux emitted from unit positive charge is

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

    B)  \[{{({{\varepsilon }_{0}})}^{-1}}\]

    C)  \[{{(4\pi {{\varepsilon }_{0}})}^{-1}}\]

    D)  \[4\pi {{\varepsilon }_{0}}\]

    Correct Answer: B

    Solution :

     According to Gauss' law electric flux \[\phi =\frac{q}{{{\varepsilon }_{0}}}\] \[\phi =\frac{1}{{{\varepsilon }_{0}}}\] \[\phi ={{[{{\varepsilon }_{0}}]}^{-1}}\]
