Which of the following statements is false about electric flux?
Electric flux is proportional to the electric field strength.
According to Gauss's Law, the electric flux through a closed surface is equal to the charge enclosed divided by the permittivity of free space.
Electric flux depends on the orientation of the surface relative to the electric field.
Electric flux is independent of the shape of the surface through which it passes.

The square of the perpendicular distance from the wire
The perpendicular distance from the wire
The square root of the perpendicular distance from the wire
The cube of the perpendicular distance from the wire
