Solved: Two parallel plate capacitors have circular
Chapter 18, Problem 19.99(choose chapter or problem)
Two parallel plate capacitors have circular plates. The magnitude of the charge on these plates is the same. However, the electric field between the plates of the first capacitor is 2.2 105 N/C, whereas the field within the second capacitor is 3.8 105 N/C. Determine the ratio r2 /r1 of the plate radius for the second capacitor to the plate radius for the first capacitor.
