We can find the electric field outside of a uniformly charged nonconducting sphere having a total charge Q by using Gauss law which states that the flux of the net electric field through a closed surface equals the net charge enclosed by the surface divided by ek.

You will use...
A non-uniformly charged sphere of radius R has a total charge Q. The electric field inside this charge distribution is described by E=Emax(r4 /R4 ), where Emax is a known constant. Using the differential form of Gauss’s law, find volume charge density as a function of r. Express your result in terms of r, R and Emax.

1.4.2 Electric field of a uniformly charged hoop Our goal here will be to find the electric field of a uniformly charged (thin) hoop. Our hoop has a charge Q uniformly distributed over a hoop with radius R, and is oriented perpendicular to the plane of the paper.

(1) Consider a very long uniformly charged cylinder with volume charge density p and radius R (we can consider the cylinder as infinitely long). Use Gauss's law to find the electric field produced inside and outside the cylinder. Check that the electric field that you calculate inside and outside the cylinder takes the same value at a distance R from the symmetry axis of the cylinder (on the surface of the cylinder) .
1.) Consider a spherical shell of radius R uniformly charged with a total charge of -Q. Starting at the surface of the shell going outwards, there is a uniform distribution of positive charge in a space such that the electric field at R+h vanishes, where R>>h. What is the positive charge density? Hint: We can use a binomial expansion approximation to find volume: (R + r)" = R" (1 + rR-')" ~R" (1 + nrR-1) or (R + r)" =R"...
