Extracted text: A parallel plate capacitor has two different dielectric materials sandwiched between the conducting plates with relative dielectric permittivities of ɛ,n=1.8 and ɛ,2=6.3 units. The materials are stacked side by side with their boundary perpendicular to the conducting plates (placed in parallel). The first material with ɛ occupies 1/4 of the area whereas the second material with Er2 occupies 3/4 of the area. The area of the plates is 5 m2 and the plates are separated by d32 mm. Find the capacitance of the system.
