Gauss's law Problem 9.2.4

Start Detector 1 Start Detector 2 Start Detector 3 Start Detector 4

Description

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.  The resolution of the detector is 1mC and the gray sphere is there for your reference only. 

Question

 Describe the charge distribution. 

Answer

 There is a uniform positive charge distribution at a radius smaller than the radius of the gray sphere and a very small negative charge distribution at a radius greater than the radius of the gray sphere.
