Question

If the number of electric lines of force emerging out of a closed surface is 1000 then tha charge enclosed by surface is

Answer 1

Answer:8.854 *10^-9 C

Explanation:

Answer 2

8.854 * $10^{-9}$ C

Explanation:

Given,

No. of field lines(ϕ) = 1000

As per Gauss' law,

ϕ = $\frac{Q_{inc} }{E_{0} }$

so, by putting the values in the above formula, we get;

1000 = $\frac{Q_{inc} }{8.85 * 10^{-12} }$

$Q_{inc}$ = 8.85 * $10^{-12}$ * 1000

∵ $Q_{inc}$ = 8.85 * $10^{-9}$

Thus, option A i.e. 8.85 * $10^{-9}$ is the correct answer.
