1. Consider a uniformly charged flat cireular disc of charge q and rádius a. Let the 2-axis be the axis of symmetry of the disc. (a) Find the potential and electric field at points on the z-axis. (b) What happens to the field if we keep the charge per unit area oa = 9/wa2 fixed, and let aoo? (c) Calculate the quadrupole moment of the disc and deduce the form of the field at large distance in any direction. Verify that on the axis it agrees with the exact value (obtained in (a)) when r/a is sufficiently large. with specific and clear cursive please!! 1.
