Question

Closed surface A is a sphere of radius R, closed surface B is a sphere of radius 2R, and closed surface C is a cube with side length R. At the geometric center of each closed surface is a small ball that is completely enclosed by the surface and carries electrical charge +q.

Assuming there are no other charged objects inside any of the closed surfaces, rank the surfaces according to the electric field line flux through them.

Rank from largest to smallest. To rank items as equivalent, overlap them.

Explanation / Answer

all surface have equal amount of total flux through them as charge encolsed by all surface is equal. gauss law.
