A square surface of side `L m` is in the plane of the paper. A uniform electric field `vec(E )(V//m)`, also in the plane of the paper, is limited only to the lower half of the square surface (see figure). The electric flux in `SI` units associated with the surface is:

Options

A. zero
B. `EL^(2)`
C. `(EL^(2))/(2 in_(0))`
D. `(EL^(2))/(2)`

Answer
