A point charge +q is at the origin. A spherical Gaussian surfacecentred at the origin encloses +q. So does a cubical surfacecentered at the origin and with edges parallel to the axes. SelectT-True, F-False, If the first is T and the rest F, enterTFFFF.
A) By symmetry, the E-Field at all points on the cubical surface iszero.
B) If the radius of the spherical Gaussian Surface is varied, theflux through it also varies.
C) The area vector and the E-Field vector point in the samedirection for all points on the cubical surface.
D) The Electric Flux through the spherical surface is greater thanthat through the cubical surface.
E) Now q is moved from the origin but is still within both thesurfaces. The total flux through both surfaces is changed.
