A square surface of side L metres is in the plane of the paper. A uniform electric field $\overrightarrow{\mathrm{E}}$ (volt/m) also in the p I an e of the paper, is limited only to the lower half of the square surface  (see Fig. 2.115). The electric flux in SI units associated with the surface is :

• A

  $\frac{{\mathrm{EL}}^2}{2{\mathrm{\epsilon }}_0}$

• B

  $\frac{{\mathrm{EL}}^2}{2}$

• C

  Zero

• D

  ${\mathrm{EL}}^2$
