The number of electric lines of force originating from a charge of 1 C is
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → \( 1.129 \times 10^{11} \)
By Gauss's law, the total electric flux through a closed surface is \( q/\varepsilon_0 \). One line of force is counted as one unit of flux, so a charge \( q \) gives \( q/\varepsilon_0 \) lines.
\( \displaystyle N = \frac{q}{\varepsilon_0} = \frac{1}{8.85\times10^{-12}} = 1.129\times10^{11} \)
