Two 4.6-cm diameter metal disks are separated by a 0.21-mm thick piece of paper. (Dielectric constant for paper is κpaper = 3.7, its dielectric strength is 16 × 10^6 V/m.)
Part A: What is the capacitance? Express your answer using two significant figures.
Part B: What is the maximum potential difference between the disks? Express your answer using two significant figures.
