\question A non-conducting sphere of radius R=2.5\,m has a non-uniform charge density that varies with the distnce from its center as given by \textrho(r)=ar\textsuperscript{1.8} (r$$x$$R) where a=2\,nC$$\cdot$$ m\textsuperscript{-1.2}. What is the magnitude of the electric field at a distance of 1.7\,m from the center?
