Number of electric lines of force emanating from $1 C$ of positive charge in vacuum is :

$8.85 \times 10^{- 12}$
$9 \times 10^{9}$
$1 / 4 π \times 9 \times 10^{9}$
$1.13 \times 10^{11}$

Question

-x3D5- from 1C of charge is -Qenclosed-x3F5-o-18-8501-xD7-10-x2212-12-1-129-xD7-1011

Number of electric lines of force emanating from 1C of positive charge in vacuum is :8.85×10−129×1091/4π×9×1091.13×1011

ϕ from 1C of charge is =Qenclosedϵo=18.8501×10−12=1.129×1011

Number of electric lines of force emanating from $1 C$ of positive charge in vacuum is :

$8.85 \times 10^{- 12}$
$9 \times 10^{9}$
$1 / 4 π \times 9 \times 10^{9}$
$1.13 \times 10^{11}$

$ϕ$ from $1 C$ of charge is $= \frac{Q_{e n c l o s e d}}{ϵ_{o}}$
$= \frac{1}{8.8501 \times 10^{- 12}}$

$= 1.129 \times 10^{11}$
