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 $\phi$_E through this surface is approximately A) zero B) 6.4 *10⁵ N · m²/C C) 13* 10⁵ N · m²/C D) 25 * 10⁵ N · m²/C E) 38 *10⁵ N · m²/C

Question

Quizplus · Accepted Answer

Since the surface has no charge enclosed, the net electric flux through it is equal to zero by Gauss's law. The orientation and size of the surface and the magnitude of the electric field are irrelevant in this case. Therefore, the best choice is A, zero.
