consider a spherical shell with inner radius R1=0.40m and outer radius R2=1.1m. the hollow insider the shell contains no charge; and charge is distributed on the inside surface of the shell and within the shell itself. such that the electrical field inside the shell itself is everywhere outward pointing and of uniform constant magnitude 40 N/C

What is the charge per unit volume at radius r=0.55m(within the material of the shell). Thanks

Let us consider a spherical Gaussian surface of radius r concentric to the shell such that *R_(1) < r < R_(2).Now applying Gauss's law, are may urrite oint vec(E)*d vec(S)=(" qenc ")/(epsilon_(0))where vec(E)= electric fieldqene = charge enclosed by the Gaussian surfaceepsilon_(0)= permiltivity of froe space=8.85 xx10^(-12)c^(2)//N*m^(2)Since bar(E) is constant and outward pointing, we get o ...
