Please solve the three parts that remain
Transcribed Image Text: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 ɛ0.The charge Q1 = 7e-8 coulombs, and the
charge Q2 = 4e-7 coulombs.
