When a 10 μC charge is enclosed by a closed surface, the flux passing through the surface is φ. Now another 10 μC charge is placed inside the closed surface, then the flux passing through the surface is .

Question

When a 10 μC charge is enclosed by a closed surface, the flux passing through the surface is φ. Now another 10 μC charge is placed inside the closed surface, then the flux passing through the surface is . (A) 4φ (B) φ (C) 2φ (D) Zero

Electric flux =(qi n c/ϵ 0) φ=(10 Î¼C/ϵ 0) If more 10Î¼C charge is placed. Electric flux =(20 Î¼C/ϵ 0)=2φ

Q. When a $10 μ C$ charge is enclosed by a closed surface, the flux passing through the surface is $ϕ .$ Now another $10 μ C$ charge is placed inside the closed surface, then the flux passing through the surface is ______.

$4 ϕ$

$ϕ$

$2 ϕ$

Zero

Electric flux $= \frac{q _{in c}}{ϵ _{0}}$
$ϕ = \frac{10 μ C}{ϵ _{0}}$
If more $10 μ C$ charge is placed.
Electric flux $= \frac{20 μ C}{ϵ _{0}} = 2 ϕ$

Q. When a 10μC charge is enclosed by a closed surface, the flux passing through the surface is ϕ. Now another 10μC charge is placed inside the closed surface, then the flux passing through the surface is ______.

4ϕ

ϕ

2ϕ

Zero

Electric flux =ϵ0​qinc​​ ϕ=ϵ0​10μC​ If more 10μC charge is placed. Electric flux =ϵ0​20μC​=2ϕ
