Question

calculate the number of electric field line originating from a charge of 1c

Answer 1

n=q/e

n=1/8.85×10^-12

n=1.29×10^11

Answer 2

Given ,

Charge (q) = 1 C

We know that ,

Gauss's theorem states that the total flux through a closed surface is $\sf \frac{1}{ e_{o} }$ times the net charge enclosed by the closed surface

$\large \mathtt{ \fbox{Φ_{e} = \frac{q}{e_{o}} }}$

Thus ,

$Φ_{e} = \frac{1}{8.85 \times {(10)}^{ - 12} } \\ \\ Φ_{e} = \frac{1000 \times {(10)}^{11} }{885} \\ \\ Φ_{e} = 1.129 \times {(10)}^{11}$

Hence , 1.129 × (10)¹¹ is the number of electric field line originating from a charge of 1 C
