Question

Total electric flux coming out of a unit positive charge put in air is

• A. ${\epsilon }_0$
• B. ${\epsilon }_0^{-1}$
• C. ${\left(4{\epsilon }_0\right)}^{-1}$
• D. $4\pi {\epsilon }_0$

Answer 1

The correct option is B ${\epsilon }_0^{-1}$

Total electric flux coming out of a unit positive charge put in air is $\frac{q}{{\epsilon }_0}$

Since, charge is unit i.e. $q=1$

$\varphi =\frac{1}{{\epsilon }_0}$
