Question

A point charge +q is at the origin. A spherical Gaussian surface centred at the origin encloses +q. So does a cubical surface centered at the origin and with edges parallel to the axes. Select T-True, F-False, If the first is T and the rest F, enter TFFFF.

A) By symmetry, the E-Field at all points on the cubical surface is zero.
B) If the radius of the spherical Gaussian Surface is varied, the flux through it also varies.
C) The area vector and the E-Field vector point in the same direction for all points on the cubical surface.
D) The Electric Flux through the spherical surface is greater than that through the cubical surface.
E) Now q is moved from the origin but is still within both the surfaces. The total flux through both surfaces is changed.

I tried
FFFTF, FFFTT

Explanation / Answer

Your mistake is on D, which is false. All statements are false so your answer should be FFFFF. D) False, the same amount of field lines exit both surfaces.
