Question

# If the flux of the electric field through a closed surface is zero:

A
the electric field must be zero everywhere on the surface
B
the electric field must not be zero everywhere on the surface
C
the charge inside the surface must be zero
D
the charge in the vicinity of the surface must be zero

Solution

## The correct option is D the charge inside the surface must be zeroGauss law:$$\phi=$$$$\oint E\cdot da=\dfrac {q_{enclosed}}{\varepsilon_0}$$Given that the flux through the closed surface is zero.$$\therefore q_{enclosed}=0$$Physics
