Question
In your hand, you currently have a spherical capacitor with a separation distance of d = 5.00 [mm] (outer
radius r = 10 [mm] and inner radius r = 5 [mm]). However, you wanted a cylindrical one instead since, personally, a spherical
capacitor looks strange to you. You decided to create a cylindrical capacitor with the same separation distance of 5.00 [mm]. What
should be the length, L, of your cylindrical capacitor if you wanted an equal amount of capacitance?
O A. 13.9 [mm]
O B. 6.91 [mm]
O C.
3.47 [mm]
O D. 2.77 [mm]
