1. Electric Charges and Fields
medium
Gauss’s law states that
A
the total electric flux through a closed surface is $\frac{1}{\varepsilon_0}$ times the total charge placed near the closed surface.
B
the total electric flux through a closed surface is $\frac{1}{\varepsilon_0}$ times the total charge enclosed by the closed surface.
C
the total electric flux through an open surface is $\frac{1}{\varepsilon_0}$ times the total charge placed near the open surface.
D
the line integral of electric field around the boundary of an open surface is $\frac{1}{\varepsilon_0}$ times the total charge placed near the open surface.

Solution
Gauss's law is applicable only for closed surface and for the charge placed inside it not near it.
Total electric flux, $\phi_{ z }=\frac{1}{\varepsilon_0} Q$
