Interpret This problem involves applying Gauss's law to find the electric flux through a sphere that encloses a given charge.
Develop Gauss's law (liquation 21.3) states that the electric flux through a closed surface is proportional to the charge enclosed. Specifically,
so given qenclosed, we can find
