Flux coming out from a unit positive charge kept in air is

Flux coming out from a unit positive charge kept in air is
  1. $\varepsilon_{\mathrm{o}}$
  2. $\left(\varepsilon_{\mathrm{o}}\right)^{-1}$
  3. $\left(4 \pi \varepsilon_{\mathrm{o}}\right)^{-1}$
  4. $4 \pi \varepsilon_o$

Solution

Flux is given by: $\phi=\frac{q}{\epsilon_0}$ If $\mathrm{q}=$ unit positive charge, $\phi=\frac{1}{\epsilon_0}=\left(\epsilon_0\right)^{-1}$
