Area of plane =.35 x. 7 = 0.245 m²

a) When plane is perpendicular to field (plane is parallel to yz plane.)

Flux = field x area

3000 x. 245 = 735 weber

b) When plane is parallel to xy plane, the plane also becomes parallel to electric field so no flux will pass though the given plane.

Flux through the plane = 0

c) Since normal to the plane makes 30 degree with x axis, it will also make 30 degree with direction of the field.

Flux through the plane

= electric field x area x cos 30

3000 x. 245 x. 866

636.51 weber.
