Flat surface area of body A=
Uniform electric field E=
Let the be the flux through the area.
a) when the electric field is perpendicular to the surface i.e =90
Now the electric flux ( )=EA cos ( )
= or
Hence 0 web is answer when the surface is perpendicular to the electric field.
b)when the electric field is parallel to the surface then =0°
Therefore
= . Or .
Hence is 15.34 web when the surface is parallel to the electric field .
