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. answer true or false

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