x a. Use Columb's law to find the electric field intensity (E) at the (0,0,h) due to a disk of uniform charge density P (0,0,h) a Ps b. An infinite sheet of charge density uniform p. is located on the x-y plane. A circular hole with radius of a, and centered at the origin, is made inside the sheet. What is the electric field intensity at (0,0,h). x (0,0,h) y
