2. Electric field created by the circular disk A charge is uniformly distributed over a think circular disk of radius R. "o" represents the surface charge density (C/m?), and hence total charge is Q = 2 TR o. In the class, we find that the ring charge (with radius r, the thickness dr, and area 2 rdr, as the figure beside) of dq = 2 ter dro creates the x-component of the electric dr field at the position P as Ρ Ε kex dEx = 2πk σχη dr.
