Document Summary

The charge of a ring with radius r and width dr is dq(r) = So the total electric field at o is, de . R (z2 + r2)3/2 dt (z2 + t)3/2. If we substitute q/ r2 with the charge area density , When r z, we have limr/z + z. So the electric field on a infinite large, uniformly charged plane is. 2s0 is a function only depends on the charge density.
