Solve the last three parts please

Three charged metal disks are arranged as shown (cutaway view). The disks are held apart by insulating supports not shown in the diagram. Each disk has an area of 2.5 m2 (this is the area of one flat surface of the disk). Use the value 8.85e-12 c2/(N-m2) for en.The charge Q1 = 7e-8 coulombs, and the charge Q, = 4e-7 coulombs. 0.02 0.02 0.02 mm 1.7 mm mm -+ --| mm 4 mm F-- A +. + +Q1 Disk 1 -Q1 -Q2 +Q2 Disk 3 Disk 2 What is the magnitude of the electric field in the region between disks 1 and 2?
