Q. Total electric flux coming out of a unit positive charge put in air is
A) $\varepsilon_{0}$
B) $\varepsilon_{0}^{- 1}$
C) $\left( 4p\varepsilon_{0} \right)^{- 1}$
D) $4\pi\varepsilon_{0}$
Explanation
(b) Total flux coming out from unit charge
$\phi = \overrightarrow{E}.d\overrightarrow{s} = \frac{1}{\varepsilon_{0}} \times 1 = \varepsilon_{0}^{- 1}$
