If we have a disc with the seven colors and rotate it at a certain RPM it will appear to us as white. That is because we can keep an image in our eyes for 1/10th of a second. If the rotation is ...

... CHECKPOINT: There is a certain net flux I through a Gaussian sphere of radius r enclosing an isolated charged particle. Suppose the Gaussian surface is changed to (a) a larger Gaussian sphere, (b) a Gaussian cube with edge length equal to r, and (c) a Gaussian cube with edge length 2r. In each cas ...
