The bar graph displays the electric flux passing through a cubical flux detector and a spherical flux detector. Observe the flux reading.
Calculate the electric field at the surface of each detector using Gauss's law. The detectors are fixed in place.
The electric field cannot be determined. Insufficient information. No symmetry.
