2 (1-√² + R² In the figure a small circular hole of radius R = 2.28 cm has been cut in the middle of an infinite, flat, nonconducting surface that has a uniform charge density a = 5.30 pC/m2. A z axis, with its origin at the hole's center, is perpendicular to the surface. What is the 280 magnitude of the electric field at point P at z = 2.51 cm? (Hint: See equation E = Number i 0.00535 Units N/C or V/m √² + R²) and us and use superposition.)
