Problem 24.5: Determine flux through spherical shells

Please wait for the animation to completely load.

Three spherical shells (red, green, and blue) are located on the screen. 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 at that point (position is given in meters and electric field strength is given in newtons/coulomb). Calculate the flux through each spherical shell. You can click-drag on the test charge to change its position. Restart.
