Question

A point charge + q is at the origin. A spherical Gaussian surface centered at the origin encloses + q. So does a cubical surface centered at the origin and with edges parallel to the axes. Select "True" or "False" for each statement below. The area vector and the E-Field vector point in the same direction for all points on the cubical surface. True False If the radius of the spherical Gaussian Surface is varied, the flux through it also varies. True False Suppose (for this statement only), that q is moved from the origin but is still within both the surfaces. The flux through both surfaces is changed. True False By symmetry, the E-Field at all points on the cubical surface is zero. True False The Electric Flux through the spherical surface is greater than that through the cubical surface. True False
