The bar graph displays the electric flux passing through a cubical flux detector and several spherical flux detectors. Drag each surface and observe flux readings.
Describe the charge distribution. The resolution of the detector is 1mC and the gray sphere is there for your reference only.
There is no net charge at a radius smaller than the radius of the gray sphere, but there is a negative charge distribution surrounded by a positive charge distribution.
