A particle of charge q is inside a nonconducting spherical shell of uniformly spread charge of Q. What is the flux through a spherical Gaussian surface concentric with the shell if the radius of this Gaussian surface is less than the shell's radius? I know we can use the formula for Gauss' Law: Flux = charge enclosed / Epsilon not. However I am not sure specifically what the charge enclosed is. Certainly there is charge enclosed of size q, however is there not a portion of the Q charge enclosed since the Q is uniformly distributed?
