please answer the question below

In the figure a small circular hole of radius R = 1.27 cm has been cut in the middle of an infinite, flat, nonconducting surface that has a uniform charge density O = 4.73 pC/m-.Azaxis, with its origin at the hole's center, is perpendicular to the surface. What is the magnitude Z. of the electric field at point Patz = 2.45 cm? (Hint: See equation E = and use superposition.) 280 72+ R- P Number Units
