An unknown charge is located on the screen along with three spherical shells (red, green, and blue)--you can only see the part of the sphere that is in the plane of the page.  A test charge is also shown that measures the electric field (in N/C) at that point (position is given in meters).  Calculate the flux through each spherical shell.  You can click-drag on the test charge to change its position.  Start
