thanks dynamicsolo. I'm starting to see how things are now

a sphere

that is what I'm confuswed about...if the insulating sphere is made of a material other than air, which one should I use on the righthand side of the flux equation? \epsilon_{0} or \epsilon. that is should I take the permittivity constant (\kappa) into account or not?

Homework Statement ok here's the problem: find the magnitude of the electric field inside uniformly charged insulating sphere of raduis R. Homework Equations application of gauss's law..but... The Attempt at a Solution should i use \phi = q_{encl}\epsilon_0 or \phi =...
