A cubical surface with no charge enclosed and with sides 2.0 m long is oriented with right and left faces perpendicular to a uniform electric field E of 1.6 × 10⁵ N/C). The net electric flux through this surface is approximately

Question

Quizplus · Accepted Answer

Since the surface has no charge enclosed, the net electric flux passing through the surface must be zero. This is because the electric flux passing through one side of the surface is cancelled out by the electric flux passing through the opposite side of the surface, due to the symmetry of the cube. The electric field only affects the charges in its vicinity and is not affected by the cube. Therefore, the correct answer is A) zero.
