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
$\varphi =\frac{q}{{\epsilon }_0}$
$\varphi =\frac{1}{{\epsilon }_0}$
$\varphi ={[{\epsilon }_0]}^{-1}$
