There exists an electric field of 100 N C⁻¹ along the X-direction. The flux passing through a square of 10 cm sides placed on the XY plane inside the electric field is N m² C⁻¹.

Question

Accepted Answer

(4) zero. Given: ⃗E=100 N C⁻¹ along X; a square of side 0.10 m lying in the XY plane. Idea: the flux through a flat surface is φ=⃗E·⃗A=EA cos θ, where θ is the angle between the field and the normal to the surface. A square lying in the XY plane has its normal along the Z-axis. The field is along X, perpendicular to Z, so θ=90°. φ=(100)(0.10)² cos 90°=0 The field lines run along the square, never through it, so the flux is zero.
