A point charge + Q is located on the x-axis at x = a,and a second point charge -Q is located on the x axis at x = -a.A cubic Gaussian surface with sides l = 3a is centered at the origin.The flux through this Gaussian surface is

Question

Quizplus · Accepted Answer

Since the Gaussian surface is symmetric and there are no charges enclosed within the surface, the electric field at every point on the surface is perpendicular to the surface. Therefore, the flux through each face of the surface is zero, and the total flux through the surface is also zero.
