Problem 24.12

Please wait for the animation to completely load.

The graph shows the flux through the expanding spherical surface (position is given in centimeters, time is given in seconds, and flux is given in N·cm²/C).  Push "play" to start the shell's expansion.  Restart. 

1. Describe the spherical charge distribution.
2. Find the equation of the electric field for the two charge distributions.
