1. The mathematical expression for the electric field due to a charged circular disc can be obtained by integrating the expression for the electric field of a ring of charge. Consider a charged circular disc with charge density that varies with radius according to sigma(r)=2r. Derive an expression for the electric field of this plate at a point a distance d=0.1m above the center of the disc if the plate’s radius is 0.3m.
