Two Infinite Non-Conducting Plates Are Parallel to Each Other,with an Interplate

Two infinite non-conducting plates are parallel to each other,with an interplate distance of d = 10.0 cm.Each plate carries a uniform two-dimensional charge density of 7.4 $\mu$ C/m².What is the magnitude of the electric field at a point located a quarter of the way between the plates?

A) 0 N/C
B) 3.14 * 10⁵ N/C
C) 4.18 * 10⁵ N/C
D) 8.36 * 10⁵ N/C
E) 1.674 * 10⁶ N/C
