Question

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

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

Answer 1

Answer: (B)

According to Gauss' law,
Electric flux $\varphi =\frac{q}{{\epsilon }_0}$
$\varphi =\frac{1}{{\epsilon }_0}$
$\varphi ={\left({\epsilon }_0\right)}^{-1}$
