Question

Which statement best explains the orientation of the surface relative to the electric field that produces the maximum electric flux, φe?" a) The surface should be parallel to the electric field lines. b) The surface should be perpendicular to the electric field lines. c) The orientation of the surface does not affect the electric flux. d) The surface should be at a 45-degree angle to the electric field lines.

Answer 1

(b) the surface should be perpendicular to the field lines

Φ = E dot A where the dot represents the dot product of the electric field and the affected area

Note: dot A represents the area perpendicular to the area A
