Two identical plates are held parallel to each other 9.14 mm apart. Each plate is circular with a radius of 51.5 cm. One plate has a net electrical charge of 0.693 microcoulomb. The other plate has a net electrical charge of -0.693microcoulomb. What is the magnitude of the electric field at a point exactly half-way between the two plates?
