I dont really understand what this part of lab, witht the graphs is asking me to do. Please help.

Figure A below shows a solid circular electrode and a solid linear electrode. Figure B shows a parallel
plate capacitor with the electric field lines drawn, The plates were charged to a 20 V potential
difference by connecting them to a power supply, In this application we are making the arbitraly
decision that the negative place will be the reference plate, and have assigned it a potential of 0 v.
