A flat thin non-conducting ring has an inner radius R1 and an outer radius R2 . The disk is uniformly charged with charge per unit area σ(>0) .

(a) What is the electric field at the center, P , of the ring? Express your answer in terms of the following variables, if necessary, R1 , R2 ,σ and the constant epsilon_0 (if needed, enter pi for π , epsilon_0 for epsilon_0 , sigma for σ , R_1 for R1 .. etc).

(b)What is the magnitude of the electric field at point A which is a distance x above the point P? The line AP is perpendicular to the plane of the ring. Express your answer in terms of the following variables, if necessary, R1 , R2 , σ , x and the constant epsilon_0 (if needed, enter pi for π , epsilon_0 for epsilon_0 , sigma for σ , R_1 for R1 .. etc).
