Question

In a closed surface, the electric flux entering and leaving out the surface are 400 Nm2/C and 800 Nm2/C respectively. What would be the charge enclosed by the surface?
Answer.
The electric flux entering in surface
ϕ1 = -400Nm2 / C
Electric flux leaving out through surface
ϕ2 = 800Nm2/C
∴ Total flux linked with the closed surface
ϕ = ϕ1 + ϕ2 = -400 + 800 = 400Nm2 / C
From Gauss’s theorem,
ϕE =
