I will have a test on problems similar to this soon and sinceour instructor, has not taken the time to really go over this indepth, I and my whole close is lost on how tosolve this problem using calculus. Any help, would beappreciated.

Find the E field and the electrical potential at the field pointproduced by the charge distributed on the concentric disks. In thediagram, the surface charge density ? 1=3x10^-7Cm^-2 for0<r<r1 and ? 2=4x10^-6Cm^-2 for r2<r<r3. r1=1m,r2=2m, r3=3m and a=5m.
